156. Calamus arctifrons Goode & Bean. Grass Porgy; Shad Porgy. 
Head 3.3; depth 2.3; eye 3.4; snout 1.9; maxillary 2.4; interorbital 3.5; preorbital 2.8; D. xn, 
12; A. in, 10; pectoral 1; ventral 1.4; caudal 1.1; scales 5-47-12. Back not greatly elevated, anterior 
profile not steep, a slight angle in front of eye; about 5 rows of scales on cheek; 8 to 10 teeth in front 
of each jaw about equally enlarged and canine-like. 
Color in spirits: Olivaceous, bluish above the trunk, with (1 or 7 obscure dark vertical bars, with 
scattering dark spots between them; similar dark spots on opercle and cheek; snout and top of head 
dark; a broad dark bar from eye straight downward across cheek; pectoral pale, ventral* mostly dark, 
color plainest inside; vertical fins with dark shades. 
The grass porgy has hitherto been known only from various places on the Florida coast from 
Pensacola and Biscayne Bay south to Key West, and has not until now been reported from the West 
Indies. The only example seen by us in Porto Rico is 7 inches long, and was seined at San Antonio 
Bridge. This is probably the smallest species of the genus, rarely exceeding a foot in length, hut is a 
good food-fish wherever found in sufficient numbers. It is usually taken with haul seines. 
While the other porgies are usually found on hard bottom, the grass porgy frequents the more 
shallow water where there is an abundance of grass or other aquatic vegetation. The limited area of 
this sort of bottom about Porto Rico doubtless accounts for the scarcity of this species.

Genus 88. ARCHQSARGUS Gill. Sheepsheads. 
Body robust, short and deep, compressed, covered with large scales. Head deep, mouth moderate, 
jaws with broad incisors in front and coarse molars on sides; incisors entire or with a shallow notch; 
posterior nostril slit-like; opercle entire. Dorsal and anal spines strong, soft parts of fin short and 
rounded; a procumbent spine before dorsal; caudal forked. Gillrakers small. Supraoccipital and 
temporal crests coalescent anteriorly, both disappearing in the gibbous interorbital area; frontal bone 
between eyes transversely convex and more or less honeycombed; temporal crest separated from 
occipital crest by an excavated area, bounded anteriorly by lateral crest, which merges into supraoc- 
cipital above eye. 
This genus, like Lagodon, Stenotomus, and C Hrynler, which show the same character of the procumbent
