21. OPHICHTHYS. 79 



r. Adiilt. Makassar. From Dr. Bleeker's Collection. Type of 

 0. hrachysoma. 



d. Adult. East-Indian archipelago. From Dr. Bleeker's Collec- 



tion. Type of 0. schaapi. 



e. Half-grown. Amboyna. From Dr. Bleeker's Collection. Type 



of P. mohiccensis. 



f. Half-grown. Philippine Islands. One of the typical specimens 



of 0. cancrivorus. 



g. Half-grown. Australia. Presented by the late Earl of Derby. 



h. Adult. Mauritius (?). From the collection of the Zool. Soc. Pro- 

 bably the type of Conger Jlavipinnatits. None of the specimens 

 transferred from the collection of the Zoological Society to that 

 of the British Museum agrees better with Bennett's description 

 than this. The end of the tail is slightly injured, so that 

 Bennett may have been deceived in determining the genus. 

 His note on the dentition is evidently incomplete. If futui'O 

 researches should prove that this species is reaUy found at the 

 Mauritius, every doubt as to the identity of C. Jlavipinnatus and 

 0. cancrivorus may be considered to be removed.
