1862. } OF FISHES FROM MADEIRA. 179 
its membrane has thirty divisions, but the rows of scales that abut 
upon it are about eighty-six in number. 
The czecal stomach was found to be of moderate length, and there 
were only two pyloric ceca. The intestine was long, having one 
convolution. No air-bladder was observed. Its colour was a uniform 
pinky red, minutely dotted with black. 
In consequence of the anterior part of the dorsal fin having been 
injured, the comparative length of the spines could not be ascertained. 
The number of the branchiostegal rays on one side is six, on the 
other seven. 
From Sebastes dactylopterus, S. kuhlii, and S. maderensis, the 
only three Madeiran species of that genus hitherto known, it is well» 
distinguished by the flatness of the head between the eyes, by the 
absence of prominent spines from the vertex, by the third (not the 
second) anal spine being the longest, by the broad membranous lateral 
line, and by the cycloid scales. From the first-named species it is 
further distinguished by the soft rays of the dorsal fin being nine in 
number, in place of twelve ; and from the two latter species by the 
black pharynx. With Sebastes filifer, Val. (Ich. Can. p. 21, pl. 2. 
fig. 2), this fish agrees in having scales with simple borders; but it 
differs (in addition to the characters by which the genus Setarches 
is separated from the genus Sebastes) in the number of the rays of 
the pectoral fin (22 in place of 16), in having, not all, but only the 
two first and the last five rays of that fin simple, in possessing five 
in place of four preopercular spines, and in the smaller scales (86 
in place of 62 along the lateral line). 
Dedicated to my friend Dr. A. Giinther, the well-known ichthyo- 
logist, to whom I am indebted for much valuable instruction. 
The following are the dimensions in inches of the principal parts 
of the specimen, which is now in the British Museum :—
