440 DR. GUNTHER ON THE FISHES OF CENTRAL AMERICA. 
sides; a black ocellus edged with rosy in the middle of the side, another larger one on 
the base of the ninth and tenth dorsal rays, and one or two small ones on the side of 
the tail. Belly covered with round brown spots; caudal with ovate black spots, 
arranged in three transverse series ; all the other fins with similar spots. 
One specimen, 23 inches long, was found by Capt. Dow on the Pacific coast of Panama. 
96. ANTENNARIUS TENUIFILIS. 
DE SyE Aravicmeks 10: 
Allied to A. bigibbus. Skin rough, the spines being exceedingly fine; anterior dorsal 
spine (tentacle) much longer than the second, and tapering into a fine point; second 
quite free, conical; third entirely covered by the skin, forming a slight protuberance. 
Rose-coloured, with black markings which are most crowded and confluent on the 
middle parts of the length of the fish, less so on the head and thorax, leaving the nape 
and back of the trunk nearly immaculate; the markings form irregular concentric 
streaks on the thorax, and larger patches on the body; a deep-black band across the 
caudal and anal fins. 
One specimen, 23 inches long, was found by Dr. Seemann, walking on the reefs outside 
the city of Panama. 
105. Exzorris MAcuLATA (Bl.). 
This species attains to a large size; Mr. Salvin collected specimens 11 inches long 
at Huamuchal. Such large examples have, of course, the eye comparatively smaller 
than younger ones; and having also a deeper body, the number of Series of scales 
between the origin of the second dorsal and the anal is increased by the addition of 
smaller scales. On such a large example Mr. Gill has founded his Dormitator microph- 
thalmus, Proc. Ac. Nat. Sc. Philad. 1865, p. 170.

D..6 a3... Aa gga Le lat. 66. 
Vomerine teeth in a broad subcrescentic band, which is more than half as broad as 
that of the intermaxillaries. Thirty-six series of scales between the occiput and the 
anterior dorsal fin; twenty between the origin of the posterior and the anal. The 
height of the body is nearly one-half of the length of the head, which is more than one- 
third of the total (without caudal). ‘The maxillary extends to below the middle of the 
eye; teeth cardiform. Caudal fin obtusely rounded, one-sixth of the total length. 
Brownish black, marbled with brown and black; fins with roundish blackish spots. 
This species differs from the others (which have been referred to the division of 
Philypnus) in having a comparatively longer head. One specimen, 8 inches long, was 
given to Mr. Salvin by Capt. Dow, who found it in the Lake of Nicaragua.
