long, and the others ranged from 91 to 138 millimeters (3% to 5)4 inches) in length. The foregoing 
catches were made on 11 dates, the greatest number of fish in one haul being five. Adult fish were 
observed by us in pound-net catches on May 25 and throughout November at Lynnhaven Roads, 
and again on October 22 at Lewisetta, Va. In the lower parts of the bay more fish were caught 
during' November than at any other period, the latest catch observed having been taken on Novem- 
ber 29; but it is taken occasionally throughout the summer. The species is nowhere abundant. 
It is eaten by the colored fishermen in at least one locality. 
The largest specimen at hand, having a length of 12)4 inches, may represent about the maxi- 
mum size attained. 
Habitat . — New York to Virginia. 
Chesapeake localities. — (a) Previous records “occurs occasionally in the southern part of Chesa- 
peake Bay” (Uhler and Lugger, 1876), Norfolk and Gloucester Point, Va. ( b ) Specimens in the 
collection: Lewisetta, Buckroe Beach, Lynnhaven Roads, and Ocean View, Va. 
Family LXXXIII.-BLENNiiD/E. The blennies 
Body moderately or greatly elongated, more or less compressed; mouth usually small, some- 
times large, never vertical; teeth various; no spines on head; skin naked or covered with small or 
moderate-sized cycloid or ctenoid scales; lateral line single, double, or absent; dorsal fin very long, 
the anterior part and sometimes the entire fin with spines; caudal fin sometimes connected with 
dorsal and anal, sometimes free; usually round; anal fin similar to posterior part of dorsal; ventral 
fins small or wanting; placed far forward (jugular) if present, composed of one spine and one to 
three soft rays; pectorals varying from large to rudimentary. Three genera of this family of small 
to medium-sized fishes are reported from Chesapeake Bay. 
KEY TO THE GENERA 
a. No fanglike or canine teeth in posterior part of either jaw; gill openings small, restricted to the 
sides, the membranes broadly united with the isthmus. 
b. Head rather pointed; snout well in advance of the forehead; upper margin of eye with or 
without a small tentacle Chasmodes, p. 332 
bb. Head very blunt; snout only a little in advance of forehead; upper margin of eye with a well 
developed tentacle Hypsoblennius, p. 334 
aa. A fanglike tooth on each side of lower jaw; gill openings wide, the membranes free from the 
isthmus, or at least forming a fold across it Blennius, p. 335 
144. Genus CHASMODES Cuvier and Valenciennes. Blennies 
Body oblong, compressed; head rather pointed; mouth large; maxillary extending to or beyond 
posterior margin of the eye; premaxillaries not protractile; teeth rather long, slender, in a single 
series, present only on front part of jaws, no canines; gill openings very short; scales wanting; a 
small tentacle on upper part of eye present or wanting; dorsal fin anteriorly, with very slender 
spines; caudal fin round, either united to or free from the dorsal; anal fin similar to soft part of dorsal; 
ventral fins jugular, with I, 3 rays; pectoral fins large. A single species is known from Chesapeake 
Bay.
