Type species Sars included two new species, S. cochleatum and S. intestinale, one of which must be the type, whereas the type species is given as Streblosoma bairdi (was Grymaea bairdi Malmgren 1866) in the Hartman catalogue (p.522), and this is followed by Fauchald, 1977 and modern authors, presumably because it is regarded as the senior synonym to Streblosoma cochleatum. However, only taxa as originally included in the genus can be type and the type species name is set by nomenclatural rules and is immutable, although the name (as later assigned by taxonomic opinion) may now be an unused synonym.
[further note added March 2017 - Hartman clearly was indirectly indicating Streblosoma cochleatum as the type of the genus as she records the type as S. bairdi and has S. cochleatum as its synonym. Verrill (1900: 661) had earlier pointed out that Grymaea was a junior homonym to a protozoan (Grymaea Fresenius, 1858) and replaced it with Streblosoma, and designated (thus by subsequent designation) the type of Streblosoma to be S. cochleatum. [details]

Etymology Not stated in the original description. The name Streblosoma is composed by the Greek root streblo, meaning 'crooked', and the Greek noun soma, meaning 'body', and seems to refer to the shape of the tubes of some specimens belonging to the new genus, described as being smooth or ''irregulariter flexuosus tortusque aut spiraliter in anfractus regulares convolutus'' (M. Sars in G.O. Sars, 1872: 413). [details]

Diagnosis Original diagnosis by M. Sars in G.O. Sars (1872: 413): ''Corpus vermiforme, subteres, postice paulo sensim attenuatum. Lobus cephalicus brevis truncatus, antice tentaculis numerosis elongatis canaliculatis, postice punctis ocularibus nullis. Segmentum buccale, primum, orem subtus circumdans, nudum. Branchiae filiformes dorso segmenti secundi, tertii et qvarti affixae, haud ramosae, utrinqve in serie contigua transversa dispositae. Fasciculi setarum capillarium modo in anteriore corporis parte, in segmentis 28—34 obvii, in segmento secundo (primo branchifero) incipientes, e tuberculis elongatis pinnulaeformibus prodeuntes. Tori uncinigeri in segmento qvinto (i. e. qvarto setigero) incipientes, breves, ovales, pone ultimum segmentum setigerum in pinnulas mutati. Setae capillares leviter curvatae, anguste limbatae, acuminatae. Uncini breves aviculares, vertice uni — vel indistincte bidentato, uniseriales. Scuta ventralia in segmentis anticis conspicua, latissima. Tubus liber, teres, arenulis aut limo obductus, aut irregulariter flexuosus tortusqve aut spiraliter in anfractus regulares convolutus.'' [details]

Etymology Not stated in the original description. The name Streblosoma is composed by the Greek root streblo, meaning 'crooked', and the Greek noun soma, meaning 'body', and seems to refer to the shape of the tubes of some specimens belonging to the new genus, described as being smooth or ''irregulariter flexuosus tortusque aut spiraliter in anfractus regulares convolutus'' (M. Sars in G.O. Sars, 1872: 413). [details]

Grammatical gender Streblosoma seems to be neuter, as 'soma' is neuter, and Sars used a neuter-ending to cochleatum as epithet, but not all authors have contributed neuter species names since. [details]

Type species Sars included two new species, S. cochleatum and S. intestinale, one of which must be the type, whereas the type species is given as Streblosoma bairdi (was Grymaea bairdi Malmgren 1866) in the Hartman catalogue (p.522), and this is followed by Fauchald, 1977 and modern authors, presumably because it is regarded as the senior synonym to Streblosoma cochleatum. However, only taxa as originally included in the genus can be type and the type species name is set by nomenclatural rules and is immutable, although the name (as later assigned by taxonomic opinion) may now be an unused synonym.
[further note added March 2017 - Hartman clearly was indirectly indicating Streblosoma cochleatum as the type of the genus as she records the type as S. bairdi and has S. cochleatum as its synonym. Verrill (1900: 661) had earlier pointed out that Grymaea was a junior homonym to a protozoan (Grymaea Fresenius, 1858) and replaced it with Streblosoma, and designated (thus by subsequent designation) the type of Streblosoma to be S. cochleatum. [details]
