Pallenopsis vanhoffenc. 
This species is conspicuously setose but readily distinguishable from 
the foregoing by the coarseness of the setae. The cephalic segment is 
longer than the two following. The abdomen is shorter than the first 
segment and clavate, with a group of long setae. Three specimens. 
Winter Quarters. 3. IV. 1902, 7. IL 1903. 
Pallenopsis setigera. 
Another conspicuously setose species. Body stout, segmentation 
indistinct, spines on lateral processes, limbs coarsely setose, with a series 
of stout spines on the propodus; terminal claw powerful with strong 
auxiliaries. Oviger club-shaped. 
Three specimens. Winter Quarters. 
Pallenopsis spicata. 
Not conspicuously setose. Body slender, scarcely so much as widely 
separated lateral processes. Three doubly pointed tubercles in the mid- 
dorsal line, tubercles also occur on the lateral processes and the first 
coxae. Oviger club-shaped. With regard to the ovigers these last two 
species are peculiar. 
Winter Quarters. 5. XII. 1902. 
Pallenopsis gaussiana. 
This may fairly called a conspicuously setose species and the dis- 
tinctive feature is the presence of a spine near the antero-lateral margin 
of the cephalon. Spines also occur on the lateral processes. The ab- 
domen is longer than the first segment. The legs are clothed with long 
coarse setae but these vary greatly in length. 
Winter Quarters. 7. IV. 1902. 385 m. 
Pallenopsis meridionalis. 
Body with widely separated lateral processes which, with the first 
coxae, bear small spines. Segmentation fairly distinct. Long coarse and 
curved setae are scattered along the legs, chiefly dorsal. 
Winter Quarters. 7. IV. 1902. 385 m. 
Ammothea. 
This genus now has a different character to that formerly obtained. 
Dr. J.C. C. Loman has called attention to the type specimen of Leach 
now preserved in the British Museum A. carolinensis. This species be- 
comes the type of the genus and if bodily form means anything those 
diminutive species with a discoid body must be transferred elsewhere. 
Ammothea is now that which in my “Discovery” Report I described as 
Leionymphon with subsequent additions.
