with a few raised transverse lines posteriorly, almost smooth 

 in front ; gastric region circumscribed, armed with two small 

 spines (occasionally four) ; the cardiac region circumscribed 

 and with several spinules on the anterior border. Lateral 

 borders of carapace four-spined, the posterior border raised, 

 and armed with from five to eight spines. Chelipedes with 

 the propodal joints flattened and a single large blunt tooth on 

 each digit. Ambulatory limbs long and slender. Tlie second 

 and third abdominal segments transversely bicarinate, the 

 fourth slightly carinate. 



Length of body (of a ? with ova) 33 millim. ; length of 

 chelipedes 39 millim. 



Loc. Station 207 [off the Pliilippines], 700 fathoms. 



Munidopsis trijida, n. sp. 



Rostrum armed with two lateral teeth, the central point long 

 and upturned. Carapace glabrous, with slight transverse 

 rugosities ; two prominent spines on the gastric region and 

 four on the lateral borders. The eye-stalks not prolonged 

 into spines. Chelipedes slender, with three rows of spines on 

 the meral joints and a single row on the inner surface of the 

 propodi. Ambulatory limbs long, the meral and carpal joints 

 with a row of spines on the upper border. Abdominal seg- 

 ments smooth, the second and third slightly grooved trans- 

 versely. 



It is allied to M. [Galathodes) latifronSy A. M.-E., and M. 

 [Galathodes] tridens^ A. M.-E. 



Length of body (of a ? ) 40 millim. ; length of chelipedes 

 47 millim. 



Loc. Station 310 [Straits of Magellan], 400 fathoms. 



Munidopsis pilosa^ n. sp. 



Rostrum long and spinulous. The body and limbs covered 

 everywhere with short densely-set hairs. Eyes rudimentary, 

 the corneee very minute, each ocular peduncle prolonged into 

 a long spine which runs parallel with but does not equal the 

 rostrum. Chelipedes very short, not twice the length of the 

 external maxillipedes. Ambulatory limbs robust, the meral 

 joints strongly spined above and below. 



Length of body (of a J' ) 24 millim. ; length of chelipedes 

 10 millim. 



Loc. Station 196 [off Gilolo Is.], 825 fathoms.
