breast, nape, cheek, and opercles scaled; lateral line complete, arched above pectoral, running on third 
row of scales from back for about 13 scales, where it drops to fifth row. 
Color in alcohol: Somewhat rosy-brown, with faint traces of darker vertical bars; anterior part of 
eye dark, head uniform rosy-brown without markings; dorsal fin with 8 broad, dark bars, the first on 
lirst 2 or 3 spines and forming a small black spot near their tips, seventh between twentieth and twenty- 
fourth spines and containing a distinct ocellus, probably blue in life; anal with 5 broad black bars, but 
no ocellus; a dark bar across base of caudal, rest of fin pale; pectoral faintly and finely barred with dark. 
This blenny reaches a length of 2 inches and is known from southern Florida (Cards Sound, Key 
West) and Porto Rico. One specimen, 1.25 inches long, obtained at Hucares, February 14, agrees in 
the main with current descriptions of this species. The dorsal spines, however, are more numerous 
and the color seems to be somewhat different. Without more material we hesitate to regard these as 
being of specific value. 
Cremnobales fasciatus Steindachner, Ichth. Beitrage, V, 176, 1876, Florida Straits. 
Auelienopterus fasciatus, Jordan <&-Evermann, 1. c., 2373, 1898. 
Genus 151. AUCHENISTIUS Evermann & Marsh. 
This genus has the form of Auelienopterus and suggests that genus strongly. It differs in the 
absence of a lateral line, in the much smaller scales, in the absence of a notch at front of dorsal fin, 
and in the union of the membrane of the anal fin with that of the caudal. Only one species known.

270. Auclienistius stahli Evermann & Marsh. 
Head 5; depth 6.5; eye 4.8; snout 6; maxillary 2.8; scales about 58, about 13 in transverse series; 
D. xLiorxLii; A. i or ii, 23 or 24; pectoral 2.5; ventral 2.2; caudal 1.3. Body elongate, somewhat com- 
pressed, especially posteriorly, dorsal and ventral outlines alike; head small, upper profile straight 
and descending; snout moderate, pointed; mouth large, maxillary reaching to or beyond middle of 
eye; jaws ecpial, heavy and projecting; teeth in lower jaw conical, short and strong, slightly recurved, 
in one row; teeth in upper jaw similar to those in lower, but a small patch of smaller teeth in front of 
jaw behind main row; teeth on vomer; gill-membranes joined to isthmus; nostrils with short tubes, a 
single flap above each eye and one on each side of nape; dorsal fin long, of spines only; last four spines 
somewhat longer than the preceding, forming a shallow notch, a feature not present in all examples; 
anal origin about midway between tip of snout and tip of caudal, fin similar to dorsal in shape, some- 
what higher in type, but a trifle lower in cotype; membrane of dorsal and anal joined to caudal ; caudal 
small, pointed; pectoral small, of 8 rays; ventral small, of 2 rays. 
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 the dorsal and anal 
dark-edged. 
This species is known only from the type, 1.2 inches long, No. 49372, U. S. N. M., from Ponce, 
February 1, 1899, and 13 cotypes, 8 from the coral and algae on the reefs at mouth of Culebra Harbor, 
February 11, and 5 from Puerto Real. 
Named for Dr. A. Stahl, of Bayamon, Porto Rico, who, under many difficulties, has made con- 
siderable collections of the natural-history objects of Porto Rico.
