(LlSITA.) 



Head 3| to 4 ; depth 4 to 4J-. D. IV-8 ; A. Ill, 9 ; scales 38-13 ; eye 4i 

 in head; snout 4; maxillary 4. Body a little slenderer and more com- 

 pressed than in Mugil curema, the back considerably arched, the profile 

 gently curved from tip of snout to front of soft dorsal. Eye moderate, 

 with a large adipose eyelid. Head broad, rounded above, the interorbital 

 width 2 1 in its length. Teeth very small, visible with a lens only. Tip 

 of lower jaw forming a right angle. Bare space between dentary bones 

 club-shaped, much larger than in Mugil curema, the subopercles barely 

 meeting below. Pectoral somewhat falcate, unusually long, reaching 

 about to base of third dorsal spine, 1 in head, its long axillary scale 

 unusually long, half length of the fin and 2% in head. First dorsal 

 inserted over middle of body, over middle of length of ventral spine ; 

 second dorsal moderate, its edge incised ; upper lobe of caudal a little 

 longer than lower, as long as head. Anal rather high ; ventrals inserted 

 before middle of pectorals. Dorsal and anal fins scaly. Color much 

 as in Mugil curema, rather greener above, sides silvery, with faint traces 

 of longitudinal streaks ; fins pale ; upper edge of pectoral and end of cau- 

 dal dusky ; a small blackish spot at base of pectoral above ; no yellow on 

 head. Length 9 inches. Pacific Coast of Mexico, not rare in Mazatlan 

 Harbor, with Mugil curema, from which the long pectoral readily distin- 

 guishes it. (hospes, a landlord, in allusion to the almost constant pres- 

 ence in the mouth of a small Oniscid crustacean similar to that found in 

 the Menhaden.)

 (RED-EYE MULLET; LIZA QJO DE PERDRIZ.) 



Head 4; depth 3f. D. IV-I, 8; A. Ill, 9; scales 35 or 36-11. Body 

 rather robust, moderately compressed. Snout rather narrow and pointed, 

 upper profile almost as oblique as lower. Interorbital space convex, 2 

 in head. Upper lip rather thick, about as in Mugil curema. Space at the 

 chin between the mandibulary bones elliptical, acutish in front and 

 behind, scarcely longer than snout. Preorbital rather narrow, covering 

 about half of the maxillary. Eyes hidden anteriorly and posteriorly by 

 a broad adipose membrane. Teeth rather wide-set, very small, not visi- 

 ble without the aid of a lens. Scales in the adult rather large, evident 

 in the young, about 20 in a line from origin of spinous dorsal to tip of 

 snout ; soft dorsal and anal densely scaly. Soft dorsal concave on its
