Station 24. 
OtflAXlHMM FROM 
TUI I»KI*OSIT. 
1^0 TirE VOYAGE OF H.M.S. CHALLENGER. 
Excluding Protozoa, over 350 specimens of invertebrates were obtained at this 
Station, belonging to about 245 species, of which 129 are new to science, including 
i\ pr* entatives of 4 new genera ; 95 of the new species were not obtained elsewhere. 
Willrmoo' Sulim writes: — “Among the worms got to-day were a fragment of an 
F.t'h >ims (?) and an animal probably belonging to the genus Chsetoderma. The latter is 
;>•> nr long and 2 mm. broad ; the pharyngeal part with the proboscis is smooth, while 
11 th. rest of tin body is covered with small spines, as remarked by Loven in specimens 
tr >m th” N< rt h Sen. At the posterior extremity the two feathered appendages described 
bv Loven could not be found, the posterior end of the body being abruptly flattened. But 
] ri.; j - these parts have been retracted, as they can be according to Loven. The mouth 
was here also ‘ in antico fine iulLito, angustum,’ and this soft part was expanded by a 
liquid of a red colour, in which Moseley saw hemoglobin. This species is probably very 
nearly allied to Chetodermanitidulum, Loven, which I have seen in Copenhagen ; it was 
• rcen by Loven on the west coast of Sweden, and by Liitken near Hellebak at the en- 
tr.incc of the Oeresund (Keferstein, Beitriige zursystematischen und anatomischcn Kennt- 
ni-- der Sipunculiden, Zeitsclir.f wise. Zool ., Bd. xv. p. 442). Being the only one got 
fi"m the deep sea, I did not dissect the specimen.” 
The Ibllowing species of Pteropoda, Ileteropoda, and Foraminifera were observed in
