snout, granular in front, and armed with a double series of barbs behind ; it is phiced

D. THE EAST INDIAN AECHIPELAGO. 



A few species only were collected by the Expedition at Banda (September 30, 1874) 

 and Amboyna (October 4). Better opportunities ofi"ered themselves during the pro- 

 longed stay of the Challenger at the Philippine Islands : Manilla was visited twice, from 

 November 4 to 11, and from January 11, 1875, to January 14 ; Zebu was reached on 

 the 18th, and its celebrated sponge-grounds were thoroughly examined; but the majority 

 of fishes were obtained at Samboangan, where the Expedition landed several times. Some 

 of the species collected there prove to be new, two being fluviatile.
