A fragmentary specimen of this species, having no tentacles and 

 only two abdominal somites, was found in the collection. It agreed 

 with Grube's description of the species in having six-toothed uncini 

 consistently throughout the body. No trace was found of the sev- 

 enth small tooth described by Marenzeller. Gills as figured by 

 Marenzeller. 



Collected at station D5157, Tinakta Island, 18 fathoms, fine sand 

 and shell bottom. 



LOIMIA, species. 



Large form having seven-toothed uncini. As the specimen was 

 incomplete — that is, the tentacles were lacking — it seemed unwise to 

 describe it as a new species.

 and shell bottom.
