Fig. 2. Quhquilius Umhatosquamis, holotype. 
nostrils bordered by a low, raised collar, the 
anterior slightly nearer the posterior than the 
groove behind upper lip. Interorbital very 
narrow, hidden in a groove between the 
raised orbital borders. No pores on the head. 
Superior borders of orbit raised in a series of 
low flaps, these bordered behind by a groove; 
behind the interorbital region this groove is 
also bordered on the side away from the eye 
by a series of raised, scalelike flaps. No 
papillae on top of head, snout, or around eye, 
but two rows following the lower portion of 
the preopercular border and extending for- 
ward below the ramus of the lower jaw; 
another weakly developed vertical row on an- 
terior portion of operculum. Gill cover free 
from the isthmus, the gill openings extending 
far forward about to below front of pupil. Ten 
widely spaced, pectinate gill rakers on the 
lower limb of the outer arch. Pseudobranch 
consisting of 5 lobes. Tongue with a broad, 
shallow median indentation as seen from be- 
low. Teeth in a narrow band in both jaws, 
some of the teeth on the inner border of the 
band somewhat enlarged; none of the outer 
teeth in either jaw especially enlarged. 
Top of head scaled forward to the eye. 
Operculum almost completely covered by 
about 12 large, ctenoid scales. A single, large, 
embedded scale on the upper portion of each 
cheek. Twenty-six scales in a longitudinal 
series from above the upper end of the gill 
cover to the base of the caudal; 6 scales in a 
transverse series. Breast in front of pelvics 
without scales. 
All of the fins with short, heavy rays main- 
tained more or less erect. First spine in both 
dorsal fins more slender than the succeeding 
rays and with a soft tip. Dorsal VI-1,7. Anal 
1,7. Pectoral without silky rays above, with 
18 rays in all; the upper 11 rays branched, the 
lower 7 simple, swollen and extending some- 
what beyond the interradial membranes. Pel- 
vics united, with a thin, smooth-edged 
frenum anteriorly. 
In alcohol the only prominent marks are 
narrow black borders to the two dorsal fins 
and a blackish bar across the caudal peduncle 
just in front of the caudal base; chromato- 
phores are scattered more or less evenly over 
the rest of the body and head, giving a plain 
gray ground color. 
So far as I can see from the species descrip- 
tions available to me Hazeus unisquamis may 
be differentiated from related forms by having 
only a single scale on the cheek, dark borders 
to the two dorsal fins, and only 7 soft rays in 
the dorsal and anal. 
Unisquamis = (L.) one scale, in reference to 
the single cheek scale.

TYPE SPECIES: Pogonymus pogognathus nov. 
Head and body depressed forward of the 
anal origin, compressed posteriorly. Head 
flat above, the eyes completely separated by a 
slightly concave interorbital area. No supra- 
orbital tentacle. Preopercular process with an
