411.— MURJEXOIDES* LacepMe. 
Butter -fishes. 
{Cenironotus BlocE: GunneJlus Cuvier.) 
(Lac^pecle, Hist. Nat. Poiss. ii, 324, 1800: type Murcenoides sujef Liac6T[). = Blenniua 
gunnelhis L.) 
Body long and low, considerably compressed, somewhat band-shaped, 
the tail slowly tapering; head small, compressed, naked or scaly; 
mouth rather small, oblique; jaws with rather small teeth in narrow 
bauds or single series; vomer and palatines usually toothless; gill- 
membranes broadly united, free from the isthmus; scales very small. 
* Little known species related to Murwnoides, recorded from Kamtschatka, and 
doubtless occurring also in Alaska, are the following : 
M. tcenia (Pallas). 
Body bauded; teeth ohtuse, subdistinct; head subtriangular, comiiressed; body 
ensiform, covered with minute imbedded scales; vent median. Dorsal fin extending 
from near the head to the tail, the spines subequal; caudal subdistinct; pectorals 
small; ventrals represented by 2 recurved spines. D. LXXXVII; A. 47. Kurile 
Islands. (PaUas.) 
(Blennius tcenia Pallas, Zoogr. Eoss.-Asiat. hi, 178.) 
M. ruherrimus (Cuv. & Val.) 
Bright red. Form of preceding; scales incouspicuons; ventrals each a single 
scarcely projecting spine ; caudal broad, rounded, distinct. D. CXV. Kurile 
Islands. (Pallas.) 
(Gunnelhis ruherrimus Cuv. & Val. xiv, 440, after Pallas, 1. c. 178.) 
M. ? oeellatus (Tilesius.) 
Brownish, marked with yellow and purple; six black ocellated spotSj along the 
dorsal fin. Caudal distinct; ventrals none. D. LXXX; A. 50. Otherwise essentially 
as in M. gunnelhis. Kamtschatka. (Cuv. Val.) 
(Ojiliidium ocellatum Tiles. M6m. Acad. St. Petersb. ii, 237, 1811: Gunnelhis apos Cuv. 
Sc Val. xiv, 426: Centronotus apus Gthr. iii, 288.) 
GUNNELLOPS Bleeker. 
« 
(Bleeker: type Blennius roseus Pallas.) 
Apparently distinguished from Murcenoides by the tapering tail, around which the 
vertical fius are confluent; palatine teeth present. 
(Gunnelhis, Gunnel, an old name of Murcenoides gunnelhis; utp, eye.) 
G. roseus (Pallas) Bleeker. 
Intensely red. Head obtuse, the lower jaw projecting; eyes large; body very 
long, compressed, tapering into a slender tail ; pectorals small, ovate, hyaline ; 2 
spines in place of ventrals; dorsal extending from the nape to the end of the tail; 
anal joined to caudal. D. ca. 100; A. ca. 90; P. 9; V. 1. Kurile Islands. 
(Blennius roseus Pallas, 1. c. 177: Centronotus roseus Gunther, iii, 290.)
