141. Pomadasis branicki (Steindachner). 
This small species, rarely exceeding six inches in length, 
was found by us in some abundance in the Astillero at 
Mazatlan. It was obtained by Gilbert both at Mazatlan 
and Panama. Steindachner described it from Tumbez 
on the coast of Peru. 
142. Pomadasis panamensis (Steindachner). 
This species is generally common along the west coast, 
but it was not seen by us. Dr. Gilbert found it both at 
Mazatlan and Panama. 
143. Pomadasis axillaris (Steindachner). Burro 
BLANCO. 
This species reaches the length of about a foot, and is 
occasionally taken at Panama: a single specimen being 
found by us at Mazatlan. Both Steindachner and Gilbert 
also record it from Mazatlan, and a single specimen has 
been found by us in the collection of Dr. Streets from the 
coast of Lower California. It has not been noticed from 
any other locality. 
144. Pomadasis nitidus (Steindachner). 
This species was found at Mazatlan by both Steindach- 
ner and Gilbert, but it was not seen by us. Gilbert re- 
cords it also from Panama. 
145. Pomadasis leuciscus (Giinther). Burrito. 
This small species seldom exceeds a length of six 
inches, and is generally common in the bay at Mazatlan, 
and on sandy bottoms where the water is shallow. We 
found large variations in the depth of body, in the width 
of the preorbital and in the length of the anal spines, but 
in no case have we been able to make these variations 
agree exactly with any of the differences by which we 
have hitherto distinguished Pomadaszs elongatus (Stein-
