Mnierpes, Jordan & Eveemann, Check-List Fishes, 468, 1896 (macrocephulus) . 



This genus is close to Labrisomtis, from which it dift'ers chiefly in the 

 very elongate body and in the absence of an orbital tentacle. The dorsal 

 spines are more numerous, and probably the vertebra? also. The lips are 

 thick and there is no trace of hook on the shoulder girdle. A band of 

 fillitorm teeth in the jaws behind the anterior series; teeth on vomer, none 

 on palatines, (/fx' /ok, moss; f'pjrvs, creeper.) 



2707. MNIERPES MACROCEPHALUS (Giiuther). 



Head 4i; depth 6 to 61 (11 in total). D. XXII, 12; A. II, 24; C. 13; P. 

 13- V. I, 3; scales about 70. The head is depressed, rather short, nearly 

 as broad as long; crown of the head broad and flat; interorbital space 

 concave, narrower than the orbit. Snout very short, obtuse, rounded ; the 

 maxillary not extending to behind the posterior margin of the orbit; lips 

 thick. Teeth in jaws forming a band with an outer series of stronger 

 ones- vomerine teeth in a narrow band; palatine teeth none. No orbital 

 tentacles, those at the nostril and on the neck very small. Gill openings 

 wide, the gill membranes being united at the throat. Head naked; 

 scales on the body not very small, cycloid. Dorsal tin commencing at 

 occiput, and terminating near base of caudal, the spines flexible, and 

 much lower than the soft rays; the 3 anterior ones rather more remote 

 from one another than the following; none of the rays of this or of the 

 other tins branched; caudal rounded; anal higher posteriorly than ante, 

 riorly, about as high as the spinous dorsal; pectorals rounded, with the 

 middle rays longest, shorter than the head; ventrals jugular, * as long as 

 the pectoral, with the spine and the outer ray enveloped in a common 

 thick membrane. Dark grayish olive; head and fins blackish; head, base 

 of the pectoral, anterior part of the body, and dorsal dotted with white. 

 Pacific coast of Central America. (Giinther.) Known from a few speci- 

 mens from Panama. Those examined by us (Mus. Comp. Zool.) have the 

 sides much freckled and mottled with pale. {futHpoi, long ; Keil>aXi^, head.)
