160 YKLI.OW 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 which 

 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, and 

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

 first dorsal is furnished with six rays, w^hich appears to be 

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

 o-enus; 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.
