MONOLENE ATRIMANA, Goode and Bean. (Figure358.) 

 Monoleite atrimana, Goode and Bean, Bull. Mus, Comp. Zoijl., xn, 155. 



Height of the body (37) is one third of the total length without the snout, and equals 

 4 times the long diameter of the eye; it also equals 1§ times the distance of the ventral 

 origin from the snout. The height at the origin of the ventrals (20) equals about •"> times 

 the length of the lower eye (0). The least height at the base of the tail (8) equals four- 

 tifths of the length of the mandible (10). The body is thin, its greatest width (4J) equal- 

 ing one half the length of the eye. 



Scales ovate or oblong, smaller than in M. sessilicauda, and without evident pectina- 

 tions. The head is everywhere seals except on the lips and the anterior half of the snout. 

 The scaling of the fins is essentially the same as in M. sessilicauda. There are 30 rows of 

 scales above, ami 32 below the lateral line on the colored side. 



The lateral line of the colored side is strongly arched in its anterior part over the base 

 and anterior third of the pectoral fin. The arc of the curved portion of the lateral line 

 (10) equals 24 times the height of the curve (4). The curve is entirely similar to that in 

 .1/. sessilicauda. The lateral line of the blind side is nearly straight, very slightly ascend- 

 ing anteriorly. There are 105 scales in the lateral line to caudal base, 18 of these in the 

 curved portion. 



The length ol the head (24) equals two-ninths of the standard length, and 2 r ; times the 

 diameter of the eye. The distance from the snout to the front of the upper eye (0) is much 

 greater than tin; distance to the lower eye (3). The interorbital area is a mere narrow- 

 ridge, whose width (1 ) equals only one ninth of the length of the eye The length of the 

 maxilla (8) equals one-third the length of the head, and on account of its oblique position 

 its hind margin does not extend much beyond the vertical through the front margin of the 

 lower eye. The length of the mandible (10) equals live-twelfths of the head's length. The 

 teeth are uniserial ami well developed on both sides. The nostrils are in very short tubes, 

 in the same line with the interorbital ridge, the posterior one beiug slightly less distant 

 from the lower eye than the anterior is from the tip of the snout. A concavity above the 

 snout. 



The dorsal fin begins upon the snout on the blind side in the perpendicular through 

 the front of the lower eye. ft contains 124 simple rays, the longest rays being in the pos- 

 terior fourth of the tin, and one half as long as the head. The anal tin begins between t he 



tips of the ventrals and under the origin of the pectoral. The vent is not on the ventral 



outline, but on the blind side and close to the beginning of the anal tin. The anal iscomposed
