One female from ^Station lOG, 1091 fathom.-., one immiture 

 in fragments from Station 107, 7o8 fathoms, and a third 

 from Station 117, 17-18 fathoms. 



cJ. A male of about the same size as that of A. Agassizii 

 figured by Prof. S. I. Smith was obtained in a previous 

 season 7i miles east of North Cinque Island, in the Anda- 

 man Sea, in 490 fathoms. It has a deeidedly less elongated 

 abdomen than A. Agassizii; its carapace has much the same 

 shape, but the rostrum shows no signs of becoming porrect 

 and reduced in length as in that species, for although it is 

 broken off just in front of the third tooth of the lower series, 

 it still extends fully to the end of the antennai scale. 



Length, from supraorbital margin to tip of telson, 83 

 millim. ; length of carapace, from supraorbital to j)o.sterior 

 margin, 23'2o millim. ; of antennai scale 15*25 millim. ; of 

 abdomen to tip of telson 59 millim. ; of telson 17'25 millim.

One fine male from Station 116, 405 fathoms. 



Colour in life crimson. 



Length, from tip of rostrum to tip of telson, 144 millim. ; 

 of carapace, from supraorbital to posterior margin, 35 millim. ; 

 of rostrum, from same point, 34 millim., from front of infe- 

 rior spine to tip 17 millim. ; of antennai scale 26 millim.; of 

 abdomen to tip of telson 75 millim. ; of telson 18 millim. 



It differs from Milne- Edwards's figure in the following 

 points : — The rostrum is of the same length as the carapace; 

 its basal spines are only four in number; the spine of its 

 inferior margin arises midway between its base and its apex, 

 and is much more nearly opposite to the middle than to the 

 apex of the antennai scale. The branchiostegal spine is con- 

 tinued backwards along the side of the carapace as a very 

 strong ridge half as long as the antennai scale. The fringes 

 of the legs are greatly developed, reminding one of those of 

 the last two pairs of legs in Serges tes. The spines of the 

 third to the sixth abdominal terga are equal. 



It difters from the specimen figured and described bv
