56 ■ THE VOYAGE OF H.M.S. CHALLENGER. 



F. THE ADMIEALTY ISLANDS. 



The visit of the Challenger to the Admiralty Islands extended from March 4 to March 

 10, 1875. The fishes collected are, as might have been expected, identical with those of 

 the Indo-Pacific Ocean. Three have proved to be undescribed, viz., a Lopliius, which 

 also occurs in the Philippines, and two Pleuronectidce ; they are inhabitants of the 

 moderate depth of 150 fathoms.

 head, the lower considerably in advance of the upper. One (male) specimen with a small 

 spine in front of each eye, another above the mouth, and a fourth at the mandibulary 

 symphysis. Snout very short, with the narrow mouth obliquely directed upwards, the 

 maxillary terminating immediately behind the front margin of the orbit. The dorsal fin
