OPHIOCAEA 71 



I have studied the following specimens, ranging in length 

 from 39 to 163 millimeters :

Balabac, 1. 



Buan Island, Sulu Province, 1.

The specimen from Camarines Sur is the largest one, 212 

 millimeters over all, and is badly diseased, the skin being greatly 

 thickened and distorted with curious, large, flattened outgrowths 

 and great warty masses. These cover the head and protrude 

 from between the scales all over the body. 



In addition, from Naganahan River, Puerto Galera, Mindoro, 

 I have eight specimens, 43 to 73 millimeters long, which are in 

 most respects typical of Ophiocara ophiocephalus of Bleeker. 

 The body has two broad whitish or yellowish crossbands, the 

 first passing from the anterior part of the second dorsal down- 

 ward and forward to the lower part of the body; the second 

 encircles the middle of the caudal peduncle; the base of the 

 caudal is marked by large spots of the same color as the bands. 

 A careful comparison fails to show any essential difference to 

 warrant the recognition of O. ophiocephalus, at least as far as 

 the Philippines is concerned. 



Specimens collected at Davao in April and at Polillo in June 

 were spawning. 



This species occurs in both fresh and salt water and is prob- 

 ably found throughout the Philippines, though apparently not 

 in as great abundance nor over such a wide range as is O. aporos. 



This species was listed from Calayan and Mindoro by Jordan 

 and Richardson; as Eleotris ophiocephalus it was listed from
