160 YELLOW GOBY. 



dorsal, and both ending together at a good distance from the 

 tail; the last-named fin round. Pectorals also round, not 

 reaching to the vent. Ventrals united, round, but with a 

 separating line causing them to appear as two, on Avhich 

 account a separate genus, as above, has been created for them. 

 The general colour is a pale yellow, with a pink border to 

 the very small scales. Slight pink bands on the dorsal fins 

 and tail; border of the ventral fins very dark. 



I have noted that this species appears to be the most heavy 

 of any Gobies that I have examined, and that there was much 

 difficulty in the attempt to count the number of the rays of 

 the fins. I supposed them to be the pectoral fourteen, anal 

 twelve, ventral ten, caudal fourteen. According to Risso, the 

 first dorsal is furnished with six rays, which appears to be 

 the usual number in most of the species in this section of the 

 genus; the second has fourteen, pectoral fifteen, anal twelve, 

 caudal fourteen, ventral ten. He says also that the pectoral 

 fins have a brown spot at their base, and a slight mark of 

 this appeared in the example we have described; but in his 

 specific character he speaks of this spot as sky blue, which at 

 least implies a tendency to variation.
