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 
the “ 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.

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 
Galateide collected by the “ Blake” Expeditions has not yet appeared, but I 
have before me the types of the ten species of Munda briefly diagnosed in his 
preliminary report which was published in 1880.* The specimens (‘‘ Blake” 
Sta. No. 36) recorded by Milne Edwards as Munida caribbeea 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 caribbea 
Stimps. by Prof. S. I. Smith+ are Munda iris of Milne Edwards. Stimp- 
son’s Munida caribbea is absolutely indeterminable from his brief notice of it,+ 
and the types were burned in the great Chicago fire. The name caribbea 
should, then, be dropped and Milne Edwards's tris and irrasa should be 
retained. 
Professor Henderson § considers Minida valida Smith to be identical with 
Munida miles A. M. Edw. On comparing the types of MZ. miles with Smith’s 
figure of MV. valida, it appears that the supraocular spines are much longer 
and more divergent in the latter than they are in JZ. miles.

In this species we see an approach to the genus P/euroncodes, since the 
sides or latero-inferior walls of the carapace are somewhat swollen, so that
