Corozal, Canal Zone, 
Type of E. minutus. 
i The numbers given are percentages of the standard length. In the counts of the second dorsal and anal rays, the first single 
ray was included, while the last two which are invariably approximated at their base have been enumerated as one. The scales 
have been counted from the upper angle of the base of the pectoral to the base of the caudal and in a transverse row from the origin 
of the anal backward to the base of the dorsal. 
EVORTHODUS MINUTUS 
Meek and Hildebrand, Publ. Field Mus. Nat. Hist. (Chicago) (Zool. ser.) 15: 870, pi. 84, 1928 
(Corozal, Panama). 
This species has been described from three small specimens obtained on the 
Pacific coast of Panama. I have reexamined the type, a well-preserved female, 
30.5 millimeters long, in the National Museum. It is somewhat chubbier and deeper- 
bodied than the average specimen of the same size of lyricus from the Atlantic coast, 
but no other essential differences are noted. The teeth have been correctly stated 
in the original description as being entire, while specimens of that size from the 
Atlantic coast, as a rule, already have the teeth notched. The determination of the 
difference in dentition between this species and lyricus from the Atlantic coast, if any, 
as well as the degree of difference in proportional measurements must wait until a 
series of adults are obtained. The measurements of the type have been included in 
the above table for the purpose of comparison. No other species of this genus is 
known at present.
