however, differs from Bleeker^s in its deeper body, longer head, more robust 
peduncle, and larger scales. The color-pattern of crescentic bands, all of 
which, except the last two, terminate on the dorsal ridge, is very distinct, nor 
is there any trace of spots on the fins. 
Family PEMPHERID^. 
EEGANICIITHYS gen. nov. 
Body deeply ovate, compressed. Seales moderate, adherent, ctenoid, - 
smooth. Lateral line continued well on the caudal fin, the tribes simple, occupy- 
ing the basal portion of the exposed scale only. Head almost wholly scaly, 
with short blunt snout and narrow preorbital. IMouth terminal, protractile, 
with wide oblique cleft, the lower jaw prominent. Jaws, vomer, and palatines 
with narrow bands of small teeth. Nostrils contiguous, close in front of the 
upper half of the eye. Eyes very large, anteromedian, high. Preorbital entire ; 
preopercle nearly so; opercle with a blunt point. One dorsal fin, rvith viii IJ 
rays, the spines graduated, the rayed portion longer than that of the anal; some 
of the anterior rays greatly produced. Caudal very large, emarginate, with 
15 branched rays, the outer produced. Anal with iii 12 rays, similar to the 
dorsal. Pectorals obtusely pointed, with 16 rays. Ventrals ivell developed, 
inserted below the base of the pectorals, close together, with a strong spine and 
5 branched raj^s. Gill-openings wide; gill-membranes separate, free from the 
isthmus ; x>seudobranehu“e large ; gill-rakers in moderate number, long and 
slender. 
Etymology : — I have much pleasure in naming this fine genus after Mr. 
C. Tate Began, B.A., of the British Musemn of Natural History, whose taxo- 
nomic vnrk has been invaluable to students of this class. 
Bcmarl’s: — Reganichihys bears a marked external resemblance both to a 
typical Pem'pheris and to the monodactyloid genus Schveitia {=Braniichthys) , 
but is at once distinguishable from both by the short anal, while from the 
latter it is further separable by the ctenoid vScales, few-rayed dorsal, and 
normally developed ventral. On the whole, therefore, I consider that its 
affinities are more with the Fcmplieridm than with the Monodactylidm and I 
have, therefore, placed it provisionally in the former family.

Dorsal and ventral contours evenly convex, the latter somewhat the 
deeper; surface of back in front of the dorsal fin transversely rounded; width
