well defined. Abdomen much like that of occidentalis. Seventh

 specimen, 7"^"^ ; width, 8""°. 



Carpus and hand coarsely and densely granulated, rugose above.

 tooth at the base of the dactyl on the large hand, and a tooth on the

Figure 18. — Eupanopeus serratus, carapace and chelipeds of No. 3019, Yale 

 Mus., X about 1.10. Phot. A. H. V. 



An unusually large male (No. 3019, pi. 16, fig. 5), which was col- 

 lected by our Yale Exped. of 1898, has been studied by Miss M. J. 

 Rathbun, who furnished the following notes : 



"Length 19.3"", width 27"", exorbital width 15.9"". Color in 

 formaline, light red and white mottled ; upper part of chelipeds a 

 darker red ; fingers a light horny brown, terminal third white. 

 Third segment of abdomen i-eaching the coxae of the last pair of 

 legs. 



This specimen demonstrates conclusively the distinctness of this 

 species from ^. occidentalis; all the lateral teeth are narrower and 

 sharper ; the areolations sti'ongly marked ; the surface rougher, the 

 short transverse granulated lines more prominent and more numer- 

 ous. The chelipeds, also, are rougher, especially the carpus." 



A somewhat larger and still better male specimen was taken in 

 1901. (No. 4068, see pi. xvi, fig. 1.) This, after preservation for a 

 few years in formol, and doubtless much faded, is pale flesh-color 

 and yellowish white, with patches of brighter yellow on the carapace 

 and chelipeds ; the upper parts of the manus and carpus are pale
