468 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. 50. 



This species is well figured and well known, having been obtained 

 bj almost all collectors in that region. 



15. PORICHTHYS POROSUS (Cuvier and Valenciennes). 



Specimens from Tome, Chile. The absence of the phosphorescent 

 organs differentiates this species from the others of the genus, and 

 might be regarded as indicating a generic difference. 



16. PARALICHTHYS ADSPERSUS (Steindachner). 



Numerous small specimens of this species from Tome and Lota, 

 Chile, the longest 120 mm. in total length, can not be separated from 

 specimens from Mexico which are in the Stanford University collec- 

 tions. Series of measurements of 12 specimens in hundi'edths of 

 body length, and careful counts, failed to show any differences, the 

 averages in each case being identical and the range of variation (which 

 was small) more or less coinciding. The specimens fitted the accounts 

 given by Steindacher in the original description very closely, as also 

 the description given by Jordan and Evermann.^ The measure- 

 ments given below are expressed in hundredths of the body length 

 to the base of the caudal. 



Dorsal rays 70 to 74; p.nal rays 56 and 57; pores in lateral line 100 

 to 120, scales in transverse series 39 to 43 (counting an oblique series 



48 to 52 

 at deepest part of body) ; head 0.29 to 0.31 ; depth 0.47 to 0.52 ; eye 0.05 

 or 0.06; interorbital space 0.02; snout 0.07; mandible 0.15 or 0.16; 

 maxillary length 0.13, pectoral length on eyed side 0.14, on blind 0.10 

 to 0.115; depth of caudal peduncle 0.10 to 0.11; gill rakers 7 or 8 + 16 

 to 19; gill raker length 0.03. 



17. CALLICLINUS GENIGUTTATUS Cuvier and Valenciennes. 



A single specimen, 20 cm. long, from Tome, Chile, is referred to this 

 species, although it differs markedly from the description given by 

 Steindachner ^ in having 56 pores in the lateral line instead of 44. 

 The coloration is much obscured by the preservation. 



Dorsal rays XXIV, 12; anal II, 21^ head 3^ in body; length with- 

 out caudal, 3f in total; depth 3| in body, 4 in total; snout 3^ in 

 head, eye 6, interorbital space 8; scales in lateral line with pores 56; 

 teeth aU coarsely conical, those on vomer in a nearly triangular- 

 shaped patch, slightly emarginate on the posterior edge; nasal, supra- 

 orbital, and nuchal tentacles present, second named split into 12 or 

 14 threads or cirri; five indistinct cross stripes of black are present, 

 most plainly on the dorsal bases ; beUy and pectoral base with many 

 small dense brown specks, these absent on the head.
