Elasmonotus, a. Milne-Edwards. 

 Elasmonotiis, A. Milne-Edwards, L c. p. 60. 



Elasmonotus latifrons^ n. sp. 



Rostrum broadly triangular, simple and flattened. Cara- 

 pace covered everywhere with rounded tubercles, the regions 

 well marked. Eyes minute, the corneje rudimentary, ocular 

 peduncles fused with the side of the rostrum. Chelipedes 

 robust, granulated. Ambulatory limbs short and robust, 

 granulated ; upper borders of meral, carpal, and propodal 

 joints with a row of blunt spines. Second, third, and fourth 

 abdominal segments transversely bicarinate. 



Length of body (of a (J) 34 millim. ; length of chelipedes 

 23 millim. 



Loc. Station 218 [off the Admiralty Islands], 1070 fathoms. 



Elasmonotus marginatus^ n. sp. 



Allied to the last ; the rostrum, however, is narrower and 

 turned up and the tubercles on the carapace larger. The 

 lateral borders of the carapace are characteristically raised and 

 project upwards and outwards. The chelipedes and ambu- 

 latory limbs are clothed with hairs and spines both on the 

 upper and lower margins, the spines being most prominent 

 on the carpal and meral joints. The second, third, and fourth 

 abdominal segments are strongly carinate transversely. 



Length of body (of a ? with ova) 50 millim. ; length of 

 chelipedes 32 millim. 



Loc. Station 168 [off New Zealand], 1100 fathoms. 



Elasmonotus Miersii^ n. sp. 



Rostrum short, with the sides parallel at first, then abruptly 

 tapering to the apex. Surface of body and limbs everywhere 

 minutely granulated. Gastric region of carapace well 

 mapped out, with two prominent blunt spines in front. 

 Chelipedes with several rounded tubercles on the inner border 

 of the meral joints. Ambulatory limbs with a row of tubercles 

 on both the upper and lower borders of the meral joints. 

 Abdominal carinee almost obsolete. 



Length of body (of a ^) 15 millim. ; length of chelipedes 

 17 millim. 



Loc. Station 173 [off the Fiji Islands], 300 fathoms. 



Elasmonotus asper^ n. sp. 



In this species the carapace is remarkably flattened and 

 covered everywhere with rough tubercles, the intervals between
