194 Messrs. J. Wood-Mason and A. Alcock on 



deciduous velvety pubescence ; in the anterior moiety of the 

 sublateral crest being reduced to a thin, interrupted, unarmed 

 wrinkle ; in the anterior or gastric moiety of the subdorsal 

 crest being broken up into a diffused, coarsish, subtubercu- 

 lose wrinkling, terminated anteriorly by a spine ; in the dorsal 

 crests being subtuberculose ; in the antennal and antero- 

 lateral spines being more divergent in a side view, or, in other 

 words, less horizontal ; in the postero-inferior angle of the 

 second and third abdominal pleura being angular rather than 

 spinose ; and, finally, in the outer margin of the dactylopo- 

 dites of the fourth and fifth pair of legs being produced near 

 the apex into a minute incurved claw. 



Two egg-laden females from Station 105, 740 fathoms. 



Colour in life delicate pink ; eyes in spirit dark purple. 



Total length from tip of rostrum to apex of telson 73 '5 

 millim. ; of carapace, from supra-orbital to posterior margin, 

 18 millim. ; of rostrum, from supra-orbital margin to apex, 

 13 millim. ; of abdomen with telson 44 millim.

14. Ephyrina Hoskynii, sp. n., Wood-Mason. 



Closely allied to Ephyrina Benedicti, S. I. Smith (= Tro- 

 piocaris planipes, Spence Bate), but differs in having the 

 carapace and the rostrum shorter, the latter not quite reaching 

 the cornese and terminating abruptly in a vertical sinuous 

 margin ; the eyes apparently smaller, and the third abdo- 

 minal segment non-produced. 



This exceedingly delicate specimen was in the fresh state 

 of a dark red colour. 



From Station 105, 740 fathoms. 



Length from front margin of rostrum to apex of telson 60

15. Hoplophorus Smithii, sp. n., W'ood-Mason. 



A small species from Station 62, 1439 fathoms, and Station 

 103, 1260 fathoms, apparently distinguished from previously 

 described species by the smallness of the spine at the postero-
