2517. PHILYPNUS LATERALIS, Gill. 



(ABOMA DE MAR.) 



Head 2ft; depth 5J. D. VI-10; A. I, 10; scales 52 to 55; eye 6 to 6 

 in head; snout 3^ to 3; maxiliary 2 to 2. Brownish, lighter or white 

 below; a distinct dark brown or blackish band extending from base of 

 pectoral to base of caudal; dorsals, pectoral and caudal dusky; ven- 

 trals and anal lighter; dorsals, caudal, and in some specimens the anal, 

 distinctly blotched. The only constant difference between this species 

 and Philypnus dormilor seems to be the brighter coloration of lateralis. 

 Streams of Pacific Coast of Mexico and Central America, from Sonora to 

 Panama, entering the sea; common, reaching a much larger size than 

 any other of our Gobies. Here described from specimens from Rio Pre- 

 sidio, Mazatlan. (lateralis, pertaining to the side.)
