Besides the type, a male, we have 4 males and 3 females of about the 

 same size with the same data. Females lack the black anal blotch, have 

 the ventral papilla more prominent, and a long vermiform oviduct. 



Monopterus cinereus Richardson.

 Not Pueumabranchus cinereus McCAe\lan<\. See Richardson, Ichthyology 

 of China, Rept. Brit. Assoc. Adv. Sci. 1845 (1846), p. 315. 

 .Measurements of Yunnan specimens are as follows: 



The two smaller specimens (and a third with imperfect tail of about 

 the same size) agree with Richardson's excellent figure in Voyage of the 

 Sulphur. The larger specimen is pale colored with occasional blackish 

 blotches. They lack evident fins. 



Monopterus xanthognathus Richardson. 



Voyage of the Sulphur, 1844, p. 118, plate 52. Canton. 

 Measurements of Fu-kien specimens are as follows: 



Total length. Head in length. Tail from vent in length. Eye in snout. 

 284 mm. 13.5 4.2 2.3 



173 13.8 3.6 2.0 



These specimens differ from cinereus just as does Reeves' figure on 

 which Richardson bases his description, in a shorter tail, smaller eye, and 

 a high gibbous nape.
