170 MEMOIRS OF THE CARNEGIE MUSEUM 



Three specimens, 56-90 mm. Crab Falls. (C. M. Cat. No. 1694; I. U. Cat. 

 No. 12067.) 



Allied to macturki, but with a distinctly larger eye and a longer and more slender 

 lower caudal lobe. 



Head 4.75-5; depth 6.5-7; D. 1,6; A. 11 to 13; adipose fin 3.33 in the length; 

 eye 2.5 in the head, its center a little behind the middle of the head; interorbital 

 5.5 in the head. 



Width of occipital crest 2.5-3 in its length, reaching dorsal plate; posterior 

 fontanel considerably wider than the anterior for a short distance, narrowed back- 

 ward; maxillary barbel reaching to near end of adipose or base of caudal; outer 

 mental barbels reaching the ventrals. 



Dorsal spine slender, equal to the third or fourth ray in height ; a few scarcely 

 evident recurved notches near the tip in front, and fine recurved teeth for nearly its 

 entire length behind; space between the dorsals considerably greater than the 

 large eye; caudal very widely forked and sometimes split to the base, the lower 

 lobe longer than the upper by nearly the length of the eye, 2.75-3 in the length; 

 pectoral spine but little shorter than head, with minute straight teeth along its 

 anterior margin to the tip, where they are replaced by recurved hooks, posterior 

 margin with about eighteen recurved spines near the tip, the spines largest near 

 the middle. 



A dark median band; dorsal hyaline, a narrow streak of chromatophores along 

 the front of each ray. 



46. Pimelodella macturki sp. nov. (Plate XVI, fig. 1.) 



Pimelodella macturkii Eigenmann, Repts. Princeton Univ. Exp. Patagonia, III, 



1910, 389. 



Type, 69 mm. Creek in Mora Passage. (Carnegie Museum Catalog of Fishes 

 No. 1695.) 



Cotypes, fourteen specimens, 46-76 mm. Creek in Mora Passage. (C. M. 

 Cat. No. 1696a-e; I. U. Cat. No. 12068.) 



Cotypes, two specimens, 66 and 65 mm. Georgetown trenches. (C. M. Cat. 

 No. 1697; I. U. Cat. No. 12069.) 



Cotypes, fifteen specimens, 49-71 mm. Choca trenches at Morowhanna. (C. 

 M. Cat. No. 1698a-d; I. U. Cat. No. 12070.) 



This species takes the place of cristata along the coast from Georgetown to 

 Morowhanna. It differs notably in the length of the adipose and barbels, the color 

 of the dorsal, and the serration on the pectoral spine.
