114 NEW FISHES FROM PACIFIC COAST GILBERT. 



less than interorbital width, equaliug distance froui vent to anal fin. 

 Veutrals with seven rays, the outer two produced, the second the long- 

 est, reaching base of seventh or eighth anal ra.\ . Pectorals witlr broad 

 base, covered with lax membrane, containing twenty-six to twenty- 

 eight rayj-, their length 1^ to If in head. 



D. 8 or 9-53 to 61 ; A. 57. Lat. 1. 100 to 110. 



Scales small, comparatively little reduced on top of head, a broad 

 riug encircling snout iu front of eyes naked, a very narrow patch of 

 scales between this laterally and premaxillaries. Scales in one hundred 

 to one hundred and ten transverse rows, eight or nine between lateral 

 line and front of dorsal. Lateral line wanting on posterior part of 

 body, iu the latter part of its course present on occasional scales only. 



Color: Uniform grayish-olive on sides, each scale, or at least its 

 marginal half, closely covered with minute dark s[>ecks. Gular and 

 branchiostegal membranes, ventral region, and axil of pectorals blue- 

 black. Basal portion of vertical fins light bluish, margined with black- 

 it^h. Pectorals dusky; veutrals blue-bla(;k at base, the distal portion 

 white. Lining membrane of mouth and gill cavity white; peritoneum 

 sih^ery, but in places so filled with black specks as to appear black. 



Many specimens, the longest 8 inches, from Stations 3045 and 2987, 

 in 184 and 171 fathoms. 



80. Physiculus nematopus sp. uov. 



Head 4 in length; depth 5. Length of caudal peduncle to base of 

 median caudal rays 5:^ in head. Snout very broadly rounded, its width 

 twice its length, which is 4f in head ; eye 3'^ ; interorbital 4 ; maxillary 

 2, reaching slightly beyond vertical from posterior margin of orbit. 



None of the teeth enlarged ; palate smooth. Branchiostegal mem- 

 branes more narrowly joined than in rastreUiger, but wholly free from 

 isthmus. Gill-rakers short and slender, eleven movable ones on hori- 

 zontal limb of arch. 



Origin of first dorsal over base of pectorals, it^ distance from tip of 

 snout 3§ in length. Base of first dorsal equaliug snout and half eye, 

 its highest ray 2^ in head. Free portion of caudal peduncle one-third 

 diameter of orbit. Notch of dorsal and anal fins not conspicuous, the 

 posterior dorsal rays little longer than those which precede, 2i in head; 

 caudal 2^^ ; pectorals 1^. Veutrals with broad base and seven rays, the 

 outer two filamentous, the second the longest, reaching base of tenth 

 to twelfth anal rays, and as long as head. Distance between bases of 

 veutrals equals interorbital width. 



D. 7 to 9-50 to 61 ; A. 59 to 64. Lat. 1. 90 to 105. 



Scales small, regularly imbricated, becoming minute on snout, which 

 they completely invest as well as mandible and gular membranes. 

 Lateral line present on anterior half of body only ; eight scales above 

 it anteriorly. 



Color : Light olive-brown sprinkled with dark specks, the sides of
