and has the branchial re^^Ion covered above with well differ- 

 entiated swollen lobes of the carapace marked longitudinalh' 

 with furrows and lines resembling the midrib and veins of a 

 lanceolate leaf. The anterior part of the rostrum between 

 the eyes is much narrower tiian in C. gii:iiihin)i/. and the car- 

 pus and meros of the cheliped are ornamented with prominent 

 rows of spines at the angles. These crabs furnish a no insig- 

 nificant portion of the food of the natives, who hunt them at 

 night with torches. So coinpletel}' terrestrial are they, that 

 thev can easily be drowned in water. x\nother crustacean 

 that enters into the dietary of the I^ahamans is the spiny \oh-

 to look at because of its bristling spines, but like man}' anotiier 

 with appalling mien, entirelv harmless, being devoid even of 

 the claws so common among its fellows. 



A large series of Mollusca was secured in the vicinity of 

 Spanish Wells, embracing most of the more familiar West 

 Indian species. Here again we lind considerable resemblance 

 to the fauna of the Dry Tortugas. The following list in- 

 cludes not only the forms collected by this expedition, but 

 also those secured in 1888. While tliere is no claim to exacti- 

 tude in the determinations, such as would attend the work of 

 a specialist in this group, it is hoped that the list as a whole 

 will serve to show the ciiaracler of the collection, and the 

 general relationship of the forms, together with some hints of 

 value concerning tlie geographical distribution of the species 

 mentioned. Cephalopoda: Spinila pcroiili Lam., a small 

 species less than an inch in diameter, with the wliorls not 

 in contact witli each other, (iastropoda: S/ronibiis g/g'(ts
