MUNIDA OBESA. 73 



point is not brought out in the figure on Plate XV., but the reader is cau- 

 tioned against inferring that there is any difference in this regard between 

 tlie " Albatross " specimens and the one figured by Milne Edwards. The 

 length of the rostral horn is somewhat variable, being often considerably 

 longer than in the specimen figured. 



MUNIDA Leach.

About forty-five species of Munida are now known. The "Albatross" 

 collection of 1891 contains five species, four of which were previously 

 unknown. Professor Alphonse Milne Edwards's final illustrated report on the 

 Galateidce collected by the " Blake " Expeditions has not yet appeared, but I 

 have before me the types of the ten species of Iliinida briefly diagnosed in his 

 preliminary report which was published in 1880.* The specimens ("Blake" 

 Sta. No. 36) recorded by Milne Edwards as Ilunida carihbcea Stimps. are the 

 same species as those described on the same page as a new species under the 

 name Munida irrasa. The specimens doubtfully referred to Munida caribbcea 

 Stimps. by Prof S. I. Smith f are 3Iiinida iris of Milne Edwards. Stimp- 

 son's Munida caribbcea is absolutely indeterminable from his brief notice of it,:}: 

 and the types were burned in the great Chicago fire. The name caribbcea 

 should, then, be dropped and Milne Edwards's iris and irrasa should be 

 retained. 



Professor Henderson § considers Munida valida Smith to be identical with 

 Munida miles A. M. Edw. On comparing the types of M. miles with Smith's 

 figure of M. valida, it appears that the supraocular spines are much longer 

 and more divei'gent in the latter than they are in M. miles.

In this species we see an approach to the genus Plevroncodes , since the 

 sides or latero-inferior walls of the carapace are somewhat swollen, so that
