ENGYOPIIRYS SANCTI-LAURENTI. 223 



are two or three short sphies. The orbital ridge is prominent around the 

 hinder half of the upper eye ; between tlie eyes the rids^e from tlie forward 

 half of the lower eye inchides a prominent spine behind wliich tlie ridge is 

 less elevated. Other angles of prominence on the head are tliat below the 

 snout, that in front of the lower orbit, and that below the angular. Snout 

 blunt, half as long as the eye. IMoutli small; maxilla curved, left reaching 

 to a vertical from the forward edge of the eye. Teeth small, hooked, in a 

 single series on the right jaws, absent from the left. Eyes large, twice as 

 long as the snout, one third of the length of the liead, close together, sepa- 

 rated by a narrow space with a sharp ridge which is divided in the middle ; 

 upper eye directly above the lower. Left anterior nostril small, with a 

 short valve ; right with a larger valve or flap. A membranous extension 

 from the opercle above the base of the pectoral. Gill rakers six, short, 

 thick, pointed, on the lower part of the arch. Lateral line bent anteriorly, 

 much as in Monolene ; bend comparatively short, two and one half times as 

 long as high, nearly straight for a short distance on the top, descending 

 farther and less rapidly backward. A sharp pelvic angle. No anal spine- 

 like process. Scales medium, ctenoid on the left side, cycloid on the right. 

 Dorsal and anal with shorter rays anteriorly, fringed in the greater portion 

 of the length. Dorsal origin on the right side near the nostril; anal orgin 

 below the base of the pectoral. Ventrals of six rays ; left fin slightly farther 

 forward. Left pectoral half as long as the head, with one or two rays more 

 than the right. Caudal pointed, four fifths as long as the head, free from 

 dorsal and anal. 



Left side clouded dark brownish ; fins blackish ; caudal with a transverse 

 series of three black spots, the median farther backward ; pectoral blackish 

 toward the ends ; right side imiform flesh color. 



The blind side of these specimens has none of the markings ascribed to 

 the types from which the original description of E. Sandi-Lmtrenii was drawn 

 by Jordan and Bollman. As the tjpes were much smaller than the present 

 individuals, it would appear from the latter as if the gridiron marks were 

 lost in age. These authors give cycloid scales as a generic character ; our 

 specimens have ctenoid scales on the left side on which the combs have 

 comparatively few and fragile teeth.
