Color in spirits: Body everywhere with a very slight yellowish tinge, in some 

 specimens a faded gray ; one specimen has traces of 10 or 12 dark crossbars; fins all 

 pale, in one case with the dorsal and anal dark-edged. 



The type, 1.2 inches long. No. 49372, U. S. N. M., from Ponce, February 1, 1899; 13 

 cotypes, 8 from the coral and algie on the reefs at mouth of Culebra harbor, February 

 11, and 5 from Puerto Real.

 in his way by Spanish authorities, made considerable collections of natural-history 

 objects of Puerto Rico. 



16. Aucheiiopterus albicaudus Everraann & Marsh, new species. 



Head 3.2; depth 4; eye 4; snout 4.1; maxillai-y 2.2; mandible 1.6; iuterorbital 

 5.3; D. XXX, 1; A. ii, 17; pectoral 1.4; ventral 1.5; caudal 1.6; branchiostegals 6; 

 scales 1-34-6. 



Body rather short, compressed ; dorsal outline not elevated ; head moderate, not 

 broad; snout short, pointed; mouth large, oblique, maxillary extending to below 

 middle of eye; lips broad, prominent; a baud of conical teeth on each jaw, thoseon 

 side somewhat enlarged and recurved; a jtatcli of teeth on vomer, none on palatines; 

 gill-membranes broadly united, free from isthmus; eye large, high up; nasal, sujira- 

 ocular, and nuchal regions with fringed tuft-like cirri; a considerable notch 

 between fourth and fifth dorsal spines, but not reaching base of membrane; longest 

 anterior spine scarcely as long as those of the posterior portion; scales large, reduced 

 anteriorly; lateral line anteriorly separated fiom the dorsal fin by ouly one scale; 

 head naked. 



Color: Uniform dark brown on head and body, no dark crossbars; dorsal brown, 

 mottled witli lighter, narrowly edged with white; a Vdack spot upon anterior 3 or 4 

 spines and a large black ocellus upon jiosterior portion of fin between twenty-second 

 and twenty-fourth spines; anal rather darker, with narrow white edge; caudal 

 peduncle black, the fin abruptly white at base, the entire fin being clear white, 

 entirely without specks; pectoral black at base, then barred with white and dark; 

 ventral black at base, the outer two-thirds barred with black and white. 



This sjiecies seems to be related to the Pacific Coast species, Anchenopterus inieg- 

 ripinnis, which it closely resembles, but difl'ers from that species in the larger scales, 

 the deeper body, and the coloration.
