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 Pomadasis elongatns (Stein-
