Etymology According to Fisher (1946) the etymology is "thalassos (sea) + ema (dart)" . According to Nishikawa (1998) Thalassema is a neuter noun. It appears to have been treated as a neuter genus by most authors. As thalassema is a noun, it cannot change suffix when first used as a species-group name (Lumbricus thalassema) and then recombined (Thalassema thalassema). Thus 'thalassemum' as if a variable adjective in Stephens & Edmonds (1972) is incorrect. [details]

From editor or global species database
Authority Lamarck (1801: 328) clearly uses 'Thalassema' as a valid genus (for his new name Thalassema rupium for the existing name Lumbricus thalassema deriving from Pallas, and he credits the genus authorship to Cuvier, but Stephen & Edmonds state they could not find evidence of this. Sherborn lists an 1801 mention of Thalassema by Cuvier in the first volume of the "Lecons .." but states the first formal mention is in Lamarck. The possible Cuvier or other authorship perhaps needs further investigation, but "Thalassema" was a pre-Lamarck name (in Pallas 1774 at least). The question is, did Pallas's mention of it (as Thalassema neptuni of Gaertner) make it an available name from that date, when it is a mention in synonymy (of Lumbricus thalassema). Nishikawa (1998:253) analysed the situation, and decided that Thalassema did date from Pallas 1774. However, it is possible the genus should be given a later date of when it appears in Lamarck (1801). [details]

Description The original mention of Thalassema by Pallas on page 8 in his Latin text, under the heading "Lumbricus thalassema", seemingly as a genus is as follows:
