1164. CHIROSTOMA ESTOR, Jordan. 
We have examined the type specinmn of Chirostoma estor. The scales are 
small and closely crowded on the region anterior to the pectoral from the 
occiput to the isthmus; they are not much reduced in size nor closely 
crowded together hetween the dorsals. The teeth on the jaws are large 
and numerous, not arranged in definite rows; there are 3 vomerine 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 2ieduucle 7J; length of 
head 31J; distance from snout to occii)ut 23; tij) of lower jaw to occii^ut 24; 
width of interorbital space 7; length of snout 12; diameter of orbit 5|; 
distance from snout to spinous dorsal 56|; insertion of spinous to soft 
dorsal 124; height of longest dorsal si^iues 7; of longest dorsal rays 11; 
distance from snout to anal 624; height of longest anal rays 12; distance 
from anal to caudal 22; length of caudal fin 184; of i)ectoral fin 17; dis- 
tance from snout to A'entral 45.1 ; length of ventral fin 104; It. Y-12 : A. 18; 
P. 14 ; scales 72-19, 9 hetween dorsals.

The type of Chirostoma estor agrees externally almost jierfectly with 
Steiudachner’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 A>fidely sejiarated, and Steindachner found no trace of the 
large vomerine teeth so conspicuous in C. estor. We therefore regard C. 
albuvi as probably a valid sj)ecies, not identical with C. estor.

Neomugil, Vaillant, Bull. Soc. Philom.,lv, 1893-1894 (June, 1894), 72 (cligueti). 
General aspect of Mucjil. 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, simjile, 
small, hut distinct; villiform teeth on vomer and 2)alatiues. Stomach 
siphonal, walls membranous, very thin in jiyloric region, hence not gizzard- 
like; a large pyloric coeca and a second smaller one; iiseudobrauchiic 
distinct. 
This genus resembles Joturus, which has the teeth llatteued and ser- 
rated, Avith only 1 series on the intermaxillary. The maxillary in Joturus 
extends not so far back. (Vaillant.) (7'£05, new; Miujil.)
