smaller species ; the carapace is shorter and narrows poste- 

 riorly, the gastric region is flatter, and the lateral borders are 

 furnished with about seven spines. The gastric spinules are 

 arranged as in M. miles. The chelipedes are short and robust, 

 the principal joints with spines arranged in three rows ; the 

 fingers are in contact throughout. The second abdominal 

 segment is alone armed with spines. 



Length of bodj (of a ^) 33 millim. j length of chelipedes 

 28 millim. 



Loc. Station 173 [south of the Fiji Is.], 300 fathoms; 

 Station 192 [off the Ki Is.], 129 fathoms; Amboyna, 100 

 fathoms. Station 200 [off the Philippines], 255 fathoms. 



Munida inornata^ n. sp. 



Allied to M. miles and M. constricta^ A. M.-E. Rostrum 

 more than twice the length of the ocular peduncles, the supra- 

 ocular spines very short (about half tlie length of the ocular 

 peduncles) and placed close together. Carapace unarmed, witli 

 the exception of very minute spines on the lateral borders and 

 a row on the anterior gastric region (of which the two be- 

 liind the supraocular spines are largest). Chelipedes in the 

 male long, narrow, and slender, very sparingly armed with 

 spines, but clothed with imbricated scales. Second abdo- 

 minal segment with two very minute spines hardly visible to 

 the naked eye. 



Length of body (of a $) 26 millim. ; length of chelipedes 

 39 millim. 



Loc. Station 219 [off the Admiralty Is.], 150 fathoms. 



Munida sancti-pauli^ n. sp. 



A shallow- water species closely approaching M. miles j 

 A. M.-E. The carapace is, however, proportionately broader, 

 the transverse strise are not so strongly marked, and the spines 

 on the lateral borders are more prominent. Only the second 

 abdominal segment is furnished with spines. 



Length of body (of a $ with ova) 28 millim., length of 

 chelipedes 29 millim. 



Loc. Off St. Paul's Rocks, 10-60 fathoms. 



Munida Haswellij n. sp. 

 Rostrum twice the length of the ocular peduncles, the supra- 

 ocular spines slightly exceeding the latter. Carapace with 

 the strias numerous, tuberculate, and the hairs densely set; 

 gastric region with two spines situated behind the supra- 

 oculars, and several spinules on the hepatic and branchial 

 areas. Chelipedes slender, the digits long and in contact
