6. CALLORHYNCHUS CALLORHYNCHUS Linnseus. 



A specimen 67 cm. in length was collected at Callao. Peru. It 

 differs in no essential characters from a specimen of this species from 

 New Zealand in the Stanford University collections. 



Bod}'' strong-l}' compressed, twice as high as thick ))elow first dorsal 

 spine, where it is one-fourth of entire length to })ase of upper caudal 

 lobe. I^ody thence tapering rapidly back to the rather slender caudal 

 peduncle. Upper anterior profile forming an e\en, moderate curve 

 to a point in front of and on a level with eye, where it is very slight!}" 

 produced. Eye contained 3f times in the space o]>liquely upward 

 from its posterior margin to base of dorsal spine, and situated mid- 

 way between dorsal spine and tip of snout (without rostral process). 

 Dental plates agreeing well with the picture published by Garman." 



Front of pectoral one diameter of eye behind front of dorsal spine. 

 Base of first dorsal contained 2f times in space between dorsals; base 

 of second dorsal equal to this space and equal to depth of l^ody under 

 dorsal spine. Posterior end of base of ventral under front of second 

 dorsal. Tip of pectoral when fin is held close to body reaches to pos- 

 terior end of ventral base. 



Color dark silvery with large, obscure, dark, round blotches on 

 upper part of side and back; one series of these along lateral line and 

 traces of one l^elow. A broken, dark band connects the dorsals and 

 is separated from its fellow of the opposite side by a light streak on 

 median line of back. A large, dusky blotch below^ eye; one on each 

 side of dorsal spine; one on opercular region, and one above base of 

 ventral. Fins all dark. These markings are all more conspicuous on 

 the New Zealand specimen.

7. FELICHTHYS PANAMENSIS (Gill). 



A specimen 20 cm. in length f i"om (xuayaquil differs from specimens 

 from Panama only in having the barbels a little longer and the dorsal 

 shield a little wider and more deeply sculptured. The width of the 

 dorsal shield measured from side to side, without considering the 

 transverse curve of the back, is one-third of the length of the head. 

 The maxillary barbel reaches to the middle of the ventrals; the pecto- 

 ral filament to the middle of the anal. 



8. GALEICHTHYS SIMONSI, new species. 



Head, 3-^ in length without caudal; depth, 5. Eye, 6g in head; snout, 

 2|; width between angles of mouth, 2]t; width of head, 1|; dorsal 

 spine, 1^; first dorsal ray, 1|: pectoral spine, 1|; ventral fin, 2^; long-
