two from Old Providence Island, flxere is ao trace of cross hands. The pre- 
valllag color Is coasidemhly darker. It Is almost aciforaly dark all over, 
except a large coasplcuoasly lighter area on side and caderside of the helly. 
The lighter area Is ahroptly dellaited from the dark shade on the hack; the 
line of d^mroation is a longitudinal th3rot;«h the upper angle of the pectoml.

and its geneml shape and appearance it agrees with the other two specimens, 
fhe scales are nearly all missing hut the traces of scale pockets left show

mstlnctlve characters and relationship . —This species shows a 
comparative high degree of divergence from airaaaitl& naradoaa (©anther), tl» 
genotype, and the two are evidently relatively remote in their relationship. 
It* differs strikingly in having the squ^^tion much less extansive 
asid in having a coi^ressed, instead of a depressed, head. Striking differenocHi 
are also found in the lateral line or^s. These structures which have been 
hitherto neglected in studios of the Imerican gobies will be considered in a 
systematic manner in a later paper. The new species differs from i)aradoxa_a l80 
in haring fewer pectoral rays.
