it " probably from Perico Island or Panama." In the present collection it 

 appears from two localities, San Josef I., Mch. 31, 1911, one specimen 

 23 inches long, and Concepcion Bay, off Ricason I., three specimens of about 

 the same size. Although these specimens differ from the description some- 

 what in proportions and coloration, the differences hardly warrant their 

 separation as a distinct species. The description of the San Josef specimen 

 is as follows: 



Body compressed, elliptical, dorsal and ventral outlines similar, depth 2.7. 

 Head large, rather pointed, 3 in body. Eye small, 3.4 in snout, 2.5 in preorbital. 

 Snout 2.4 in head. Gape of mouth 4.5 in head. Teeth whitish, the tessellation 

 evident; central suture prominent; posterior canines moderate, 2 on one side and 2 

 and a rudiment on the other. Scales on cheek in two and a half rows. Scales of 

 body 2\, 25, 6|; six before dorsal. Dorsal IX, 10; the highest spine 2.9 in head, the 

 highest ray 2.6. Anal II, 9, increasing slightly in height posteriorly, the longest ray 

 3 in head. Pectoral narrowly rounded, 1.4 in head. Ventrals pointed, nearly 2 in 

 head, reaching a little more than half way to vent. Caudal peduncle long and 

 rather slender, 2.4 in head. Caudal fin with nearly straight hind margin, but its 

 angles much exserted and pointed, projecting a distance equal to .4 of the head 

 beyond the median portion of the fin. 



Color in spirits, uniform yellowish white, except for a faint indication of length- 

 wise stripes on the sides below and dusky marks about the lower jaw; central rays 

 of caudal very narrowly tipped with dusky. 



The following color notes in life were made by Dr. Chas. H. Townsend when the 

 specimen was taken: Pale cream or milky white color, with all markings in pale light 

 blue. Blotches around orbit ; fins, except ventrals, all bordered (only the upper edge 

 of the pectoral so marked), a spot at the base of the caudal, and about five striped on 

 the side, all of this color. 



Callyodon compressus sp. now 



Fig. 13. 



Body much compressed, deep, 2.5 in length, lower outline more arched than 

 upper. Head 3, moderately pointed, slightly humped over the eyes. Eye 3.7 in 

 snout, 8.5 in head, 2.2 in preorbital, vertical distance above eye one half that from 

 eye downward. Gape of mouth 4 in head. Snout 2.3. No canine teeth present. 

 Scales on cheek in two and a half rows, 6, 5, 2, those of the upper row somewhat 

 larger. Scales of body 2§, 25, 6§; six before dorsal. 



Dorsal IX, 10, about even throughout its length, highest spine 2.4 in head, 

 longest ray 2.6. Anal II, 9, longest ray 2.5 in head. Pectoral pointed, extending 

 beyond tips of ventrals, 1.4 in head. Ventrals 1.6 in head, extending more than half 

 way to vent. Caudal weakly lunate, its outer rays scarcely exserted. Caudal 

 peduncle deep and compressed, its least depth 2 in head. 



Color in alcohol, brownish, slightly darker along back; dorsal, caudal and anal 

 fins dusky, the anal with a lighter margin. Paired fins pale. Teeth whitish, with _ 

 indications of rosy toward the base.
