81. Eupanopeus occidentalis (Saussure)? 

 Tortugas. Two young. 



Genus Micropanope Stimpson. 



Carapace of moderate width, panopeiform; usually granu 

 lous or spinulous. Of the antero-lateral teeth, E is reduced 

 or wanting, S is much reduced; antero-lateral margin spinu- 

 lous; ambulatory legs spinulous on superior or anterior mar- 

 gin in cypical species. 



Type, M. sculpttpes Stimpson. To this genus I refer 

 ccanthiformis (A. Milne Edwards as Panopeus), lobifrons A. 

 Milne Edwards, truncatifrons, sp. nov., an undescribed species 

 from the Pacific coast, and latimanus and cristimanus Stimp- 

 son which I have not seen. 



82. Micropanope xanthiformis [A. Milne Edwards'). 

 Station 41, off Sand Key, 15 fathoms; one male. 



Micropanope truncatifrons sp. nov. PI. iv, Fig. 2. 



Coarsely granulate; frontal lobes truncate. 



Carapace moderately convex; antero-lateral teeth horizontal. 

 Surface granulate, granules large and conspicuous anteriorly, 

 diminishing toward the posterior margin. Regions well de- 

 fined. On each protogastric region there is a short, oblique 

 ridge; a longer ridge on each hepatic region; a transversely 

 arcuate elevation on the anterior part of the branchial region. 

 Outer orbital tooth very small and well separated from the 

 second tooth which is small and tuberculiform. Third, fourth 

 and fifth teeth dentiform, the third directed forward, the fourth 

 and fifth outward, the fifth smaller than the two preceding. 

 Margin of teeth denticulate. Front truncate; margin thin, 

 finely crenulate; lobes under the lens slightly sinuous; a row 

 of coarse granules behind and above the margin giving the 

 front the appearance of having a double edge. Orbital mar- 

 gin granulate; two superior fissures little marked, inferior 

 margin with two subequal teeth and a broad outer V-shaped 

 fissure. Inferior surface of the carapace granulate. 



Chelipeds unequal in the female, tuberculate. Merus short
