During the long vacation at the end of the University year 

 1912-13, a joint expedition from the University of the Philip- 

 pines and the Bureau of Science was made to Palawan Island 

 in the interest of biological study. The party proceeded to 

 Taytay, a village of about 30 houses on a bay of the same 

 name. From the Coast and Geodetic Survey, I had learned 

 of the presence of a lake supposed to be south westward of. 

 Taytay. Exploration led to the location not only of one lake 

 near Taytay, but of two, one of them, however, being more of 

 a swamp full of grass than a lake except in the rainy season. 



Lake Manguao is about 5 kilometers long from east to west 

 and from 2.5 to 3 kilometers wide from north to south. The 

 greatest depth discovered was 7 fathoms, a little to the south- 

 east of Bamboo or Cemetery Island, between the island and 

 the shore. There are very many islands in the lake, perhaps 

 as many as 25. These vary in size from a mere point of rock 

 to those having an area of perhaps 1 hectare. 



Two trips were made to the larger of these lakes, Lake 

 Manguao, from which the new species of fishes, described in 

 this paper, were taken. With the exception of the shore along 

 the south side of the lake, which was mainly a sandy beach, 

 there was a shelving shore and small rock fragments, in many 

 places falling precipitously into the water. Some of the fishes 

 were taken from the extreme northeastern part of the lake 

 nearest to the town of Bantolan, but most were taken on the 

 western side near the site of the second camp. Many of the 

 larger fishes were readily caught with hook and line. The 

 smaller ones were taken in large numbers on a small net of 

 cheesecloth baited with cooked rice. This was placed in shallow 

 water and raised when a considerable number of fishes were 

 feeding above it. 



In this paper, "length of body" is the distance from the 

 tip of snout to the end of the caudal vertebrae; "length of head" 

 means from the tip of snout to the posterior margin of the 

 hard opercle; "length of caudal peduncle" covers the distance 

 from the posterior margin of anal to the uncovered ventral 

 margin of the caudal fin ; "length of snout" refers to the distance
