330 Surg.-Capt. A. Alcock on 



The anterior abdominal terga have a faint naked trans- 

 verse groove. 



The eye-stalks, which are slender and comparatively long, 

 are not prolonged beyond the globular corneae, are not united, 

 and are freely movable. 



The inflated basal joint of the antennulary peduncle has 

 only one of its spines, namely that at the antero -external 

 angle, long. 



The antennary flagellum is not much longer than the 

 chelipeds (in the female). 



The ischiopodite of the external maxillipeds has the inner 

 edge evenly toothed and the lower edge prolonged distally 

 into a huge spine, while the meropodite has two strong spines 

 on the lower edge in the proximal half. 



The thoracic legs, except the fifth pair, are thickly covered 

 with long hairs. The chelipeds are long, slender, and 

 slightly asymmetrical, the longer one exceeding the length of 

 the fully extended body (with the rostrum) by the extent of 

 the dactylopodite ; their ischiopodite has two strong distal 

 spines, one above, the other below, their meropodite two rows 

 of spines along the upper and inner surface and a terminal 

 ring of four spines, and the carpopodite lias a terminal ring of 

 three spines ; the slender fingers, which are finely and evenly 

 toothed to the very tip, slightly exceed the elongate palm in 

 length. 



The second, third, and fourth thoracic legs are relatively 

 short, the second pair barely, and the others less than, half 

 the length of the chelipeds ; in all the meropodite and carpo- 

 podite have the anterior edge spinate, and the dactylopodite 

 has the terminal claw but slightly curved and very much 

 longer than the spines along the posterior edge. 



An egg-laden female from Station 112, 561 fathoms, 

 measures 44 millim. from the tip of the rostrum. 

 Colours in life uniform milky orange. 



82. Munidopsis scobina, sp. n. 



Nearest to M. ei'inacea, A. M.-Edw., J/, spinifera, A. 

 M.-Edw., and M. Agassizii^ Faxon. 



Body and appendages almost devoid of hairs, but with the 

 spinaturc sharp and distinct. 



The greatest breadth of the carapace is about six sevenths 

 of its length. The rostrum, which is styliform and slightly 

 recurved at tip, is not quite half the length of the carapace; 

 the frontal border is very slightly oblique and, except for one 

 or two small spinelets above the base of the anteiniaj, is
