4. CRYSTALLIAS M ATSUSHIM^E Jordan and Snyder, new species. 
Head -i^ in length; depth tt^; snout 3i in head; eye 3i; interorbital 
space 2f ; D. 58; A. 51; P. about 31. 
Body and head markedly compressed; upper profile of head rather 
abrupt in front; mouth inferior, oblique; the maxillary extends to a 
point below anterior part of iris. Teeth small, trilobed; the lateral 
lobes minute, larger on posterior teeth, scarcely discernible or absent 
on anterior ones. E3^e large, directed laterally, situated a little nearer 
to tip of snout than to gill opening. Snout apparently without pores; 
three or more small, fleshy barbels on each side of upper and lower 
jaws; those on upper jaw slightly longer than those below, both groups 
located on the part of jaw anterior to angle of mouth. Nostral single, 
with a large tube located in the position occupied ])y the anterior 
nostril in Liparis. Gill opening small, entirely above base of pectoral 
fin. No lateral line can be detected. 
Fin rays enveloped in a gelatinous, fleshy covering which grows 
thinner posteriorly where the rays are more exposed to view. Dorsal 
fin beginning just above gill opening, the rays growing graduall}''

higJaer posteriorly to near the caudal fin, where they become shorter; 
anal inserted behind beginning of dorsal, a distance equal to one-half 
the length of head, similar in shape to dorsal; both dorsal and anal 
continuous with caudal, the latter rounded posteriorly. Pectoral large, 
its edge divided by a shallow notch, the two parts thus separated being 
broadly rounded; the fin extends forward below to the anterior middle 
portion of ventral disk. Ventral disk small, round; its edge free. 
Color translucent; head and body with narrow dark l)ars and oblong 
spots. The bars, 7 to 8 above, 5 below, have their origins near median 
line of bod}', where they are darkest and better defined; passing outward 
they become less distinct and disappear near edges of fins. A row of 
4 or 5 spots on upper edge of fin, 2 spots near middle of body, several 
spots and bars on upper part of head.
