5o() ZOOLOGY OF THE FAR IvVST. 
I wish to express my great indebtedness to Dr. Nelson Annnndale for placing 
this valued collection in my hands to stud}' and report. 
SALANGIDAE. 
Leucosoma chinense (Osbeck). 
Ice fish. Chinese White Bait. 
Head 4! to 5|; depth if to 2^ in head ; D, iii, 10 to iii, 18; A. ir or m, 25 to 
29 (23 in young); P. i, 22 to 24. 
Body greatly compressed, deepest at dorsal origin. Caudal peduncle well 
compressed, least depth about half its length or 4I to 5I in head. Head strongly 
depressed, width 2 to 2^ in its length, snout greatly depressed ; 3^ in head, measured 
from upper jaw tip. Eye large, partly ventral, less than snout and 2 in interorbi- 
tal. Maxillary reaches opposite middle of eye ; to 2f in head (from tip of upper 
jaw). Row of short strong teeth along each maxillary edge and large teeth in row 
along each mandibular edge. Interorbital broad, level, about \ of head (from tip of 
upper jaw). Gill-opening extends forward opposite hind edge of pupil. Gill-rakers 
2-1-13, lanceolate, about as long as gill -filaments or | of eye. Dorsal origin midway 
between gill-opening and caudal base; first branched ray if to 2 in total length of 
head. Anal inserted entirely behind depressed dorsal and little nearer caudal base 
than ventral origin ; first branched ray I'l to i§ in total head. Caudal forked, little 
shorter (damaged) than head. Pectoral if to 2| in head. \'entral inserted much 
nearer pectoral origin than anal, depressed fin not reaching opposite dorsal origin, 
I ^ to if in head. Adipose fin small, above last fourth of anal. Uniform brownish, 
scarcely paler below. Length to 175 mm. 
Thirteen examples, v^mall examples all have a sliort snout Jind much fewer 
dorsal and anal rays. 
MONOPTERIDAE. 
Fluta alba (Ziuew). 
One example 427 mm. Brown above, lower surface ])aler to whitish 
ANGUHJJDAE. 
Anguilla japonica (Schlegel). 
Head 7/0 to 8g ; depth 19^ to 21*; snout 5 to 5f in head measured from upper 
jaw tip ; ej^e io| to 13^ ; mouth cleft 3* to 4; interorbital 5 to 5f ; pectoral 2| to 
3^. Length of head less than space between dorsal and anal origin. Angle of mouth 
behind hind edge of eye. Lips thick. vSpace between dorsal origin and vent 2| to 2| 
in predorsal space. Predorsal region 3^ to 3f in total length. Largeh^ uniform 
brown, but little paler below. Length 281 to 350 mm. 
Two examples.
