BULLETIN 97, UNITED STATES NATIONAL MUSEUM. 





Material examined. — See table. 



Remarks. — The resemblance of the St. Thomas 

 specimens to the figures of Edwards and Bouvier 

 cited leads me to believe that it is the same 

 species, granting, however, that in their plate 9, 

 figure 2 (my fig. 122a), the most prominent lobe 

 on the inner portion of the orbit is the pterygos- 

 tomian lobe, and the one overlying it, the lobe of 

 the exognath; the pterygostomian lobe conceals 

 the lobe of the orbit, but in the St. Thomas 

 specimen the outer corner of it is visible in 

 ventral view.

Diagnosis. — Ambulatory legs of second pair 

 twice as long as width of carapace, of first pair 

 in mature male clothed with shaggy hair on pos- 

 terior margin of propodus and proximal half of 

 dactylus. Lobes on anterior margin of carpus 

 of ambulatory legs well marked. Pterygosto- 

 mian lobe advanced, far exceeding inner sub- 

 orbital lobe. Front bilobed. 



Description. — C a r a p a c e very rough with 

 coarse granulation. Front divided by a wide 

 and deep V-shaped notch into two lobes, each of 

 which is faintly emarginate. Two supra-orbital 

 lobes triangular, obtuse. Outer orbital tooth 

 long and narrow, with nearly straight margins 

 and directed obliquely forward and outward. 

 Lateral teeth tAvo, distant, of subequal length, 

 blunt (acute in the j'oung), directed outward 

 and only slightly forward. Crest above pos- 

 terior margin sinuous, broken into seven irreg- 

 ular scallops. Outer suborbital lobe transverse 

 and slightly convex. Lobe at angle of buccal 

 cavity rounded and produced far beyond inner
