1154. CHIROSTOMA ESTOR, Jordan. 



We have examined the type specimen of Chirostoma estor. The scales are 

 small and closely crowded on the region anterior to the pectoral from the 

 occiput to the isthmus; they sire not much reduced iu size nor closely 

 crowded together between the dorsals. The teeth on the jaws are large 

 and numerous, not arranged in definite rows; there are 3 vouierine teeth 

 almost as large as those on the jaws. 



Some exact measurements of the typo, expressed in hundredths of the 

 length of the body, are here given : 



Length of body in millimeters 212 ; depth of caudal peduncle 7| ; length of 

 head 31 ; distance from snout to occiput 23 ; tip of lower jaw to occiput 24 ; 

 width of interorbital space 7; length of snout 12; diameter of orbit 5 ; 

 distance from snout to spinous dorsal 56; insertion of spiuous to soft 

 dorsal 12|; height of longest dorsal spines 7; of longest dorsal rays 11; 

 distance from snout to anal 62|; height of longest anal rays 12; distance 

 from anal to caudal 22; length of caudal fin 18; of pectoral fin 17; dis- 

 tance from snout to ventral 45 i ; length of ventral fin 10; D. Y-12: A. 18; 

 P. 14 ; scales 72-19, 9 between dorsals. 



1154 (a). CHIROSTOMA ALBUM (Steimlachner). 



The type of Chirostoma estor agrees externally almost perfectly with 

 Steindachner's account of Chirostoma album from Lake Patzcuaro, a 

 species which he later places in the synonymy of C. estor. But the type 

 localities are widely separated, and Steindachner found no trace of the 

 large vouierme teeth so conspicuous in C. estor. We therefore regard C. 

 album as probably a valid species, not identical with C. estor.

368 (a). NEOMUGIL, Vaillaut. 

 Neomvgil, VAILLANT, Bull. Soc. Philom., iv, 1893-1894 (June, 1894), 72 (digueti). 



General aspect of Mugil. Mouth widely cleft, maxillary extending 

 beyond anterior edge of orbit. Fine teeth in many series in each jaw, 

 those of outer series on intermaxillary most developed, all conical, simple, 

 small, but distinct; villiforin teeth on vomer and palatines. Stomach 

 siphonal, walls membranous, very thin in pyloric region, hence not gizzard- 

 like; a large pyloric cceca and a second smaller one; pseudobrancliiu- 

 distinct. 



This genus resembles Joturus, which has the teeth flattened and ser- 

 rated, with only 1 series on the intermaxillary. The maxillary in Joturns 

 extends not so far back. (Vaillaut.) (veos, new; Muyil.}
