50 GOBIES OF THE PHILIPPINES 



anal had alternate rows of blackish and pale spots on the rays, 

 with a pink margin; caudal was pale at its base, with dark or 

 blackish rays and clear membrane. 



Several living specimens, from 90 to 105 millimeters in length, 

 from the same locality, were dark olive green, with greenish 

 yellow on the lips, about the nostrils, and over a large part of 

 the preopercle. On the lower half of the body the longitudinal 

 rows of spots were brick red ; a broad, bright brick red margin 

 on ventrals and anal; in other respects the colors were as al- 

 ready given. The red colors were very noticeable owing to 

 the habit these fishes have of attaching themselves head down- 

 ward to the glass front of the aquarium. They prefer fasten- 

 ing themselves by their ventrals to vertical objects, such as 

 water pipes or rubber tubing, to lying on the bottom. In this 

 way they are fairly well concealed and out of the way of other 

 fish. 



In alcohol the colors are similar, but the rows of white or 

 pale spots on the sides are more conspicuous until the lapse of 

 years makes the fish a more uniform yellowish brown ; the sides 

 of snout and cheeks covered with few to many dark brown or 

 black spots; the ventrals black with a pale or whitish outer 

 margin; the other fins black or very dark, except the caudal, 

 which has a whitish or pale band along its upper margin, this 

 widest toward the rear; the pink spots on the pectoral are 

 white or whitish.

 mens had been examined, from Pasig River, Manila, and a large
