Mr. J. Y. Johnson on new Fishes from Madeira, 73 
not elongate. Some of the rays have denticulate edges. At the 
upper base of each fin there is a free white ovate appendage of bone, 
nearly seven times as long as wide, resembling in shape the wings 
of some insects. The surface is obliquely striate, and the sharp 
edge of the anterior margin is set with a few distant minute teeth. 
At its base there is a small process directed backwards. The vent 
is in front of the middle of the total length, and the anal fin begins 
immediately behind it. The ¢ai/ is compressed, and a little longer 
than high. The caudal fin is forked. 
There is no lateral lme. A series of about sixty scales may be 
counted between the opercle and the caudal fin, and about fifty in 
- the height. 
The individual was obtained in the month of January. The ver- 
tical fins appeared to have suffered damage, and nothing can be 
positively asserted in regard to certain points which it is desirable 
to know, such as the height and outline, and the structure of the 
rays. Neither could it be ascertained whether they had been covered 
with scales ; but it may perhaps be inferred, from the spinous sides 
of the rays, that this had not been the case. The rays of the ventral 
fins seemed to be ten; but whether these were really only five rays 
split to their bases I could not make out with any degree of certainty. 
No connecting membrane was to be seen between the first five spines 
of the dorsal fin, but it may have been removed by accident. The. 
fish had fed on animal food. 
The following table shows the dimensions of the principal parts 
of the specimen,-which has been sent to the British Museum :—
