58 NEW FISHES FROM PACIFIC COAST— GILBERT. 



increasing in lieigbt posteriorly, and meeting around end of tail in a 

 well-developed fin. Pectorals well developed, 3^ in head. 



Color uniform, yellowish-olive on body and fius, finely dotted with 

 black. 



Several specimens taken at station 3035 (30 fathoms); the longest 6 

 inches. 



This species seems to be nearly related to Leptoconger perlongus Poey, 

 which has, however, the dorsal begiuning much nearer the head, and 

 the anterior nostril tubular. 



12. Ophichthys nothochir sp. nov. 



Closely related to 0. evionthas, differing chiefly in the obsolescent 

 j>ectoral fius and in the color, evionthas being finely spotted. 



Teeth conical, compressed, directed backwards in a single series in 

 jaws and on vomer, smaller in size on the latter; "nasal teeth" in a 

 V-shaped series. 



Mouth small, its cleft extending but little behind the eye, its length 

 2^ in head. Anterior nostrils in a well-developed tube without project- 

 ing flap. Posterior nostrils without tube, their posterior end under 

 front of orbit. 



Snout 4 in head, the upper jaw projecting for a distance equaling 

 two-thirds the diameter of orbit. Eye half length of snout, its anterior 

 margin over middle of cleft of mouth. Gill slit ^ in head. 



Pectorals nearly obsolete, represented by a small triangular, appar- 

 ently rayless flap, less than one-third diameter of orbit, and one- 

 fourth gill slit. 



Origin of dorsal behind gill slit a distance equaling half that from 

 gill slit to front of eye. 



Head and trunk longer than tail by a distance about equaling length 

 of snout. Head 4=^ in trunk. 



Color : Middle line of back with a series of twelve elliptical yellow 

 spots, their length varj'ing from once to twice the diameter of eye, and 

 separated by wide intervals ; each spot is surrounded by a black ring, 

 coalescent below with a large elliptical black blotch on middle of sides, 

 these varying somewhat in size and shape. The intervals between 

 these spots are marked with round black spots about the size of pupil. 

 Similar spots, but larger, are scattered on sides of belly and under side 

 of tail ; middle of belly with fainter spots and markings. Head closely 

 covered with round or polygonal black spots about as large as eye, 

 around which are reticulations of light yellow. 



Several specimens from San Josef Island, Gulf of California; the 

 largest 14 inches long. 



13. Exocoetus xenopterus sp. nov. 



Diagnosis : Snout short, without barbels. Strong bands of teeth on 

 vomer and palatines. Pectorals elongate, nearly reaching base of cau-
