Show 458 MR. J. Y. J O H N S O N O N S O M E N E W [June 3, adipose dorsal. The pectorals are placed low down, are narrow and pointed; they are much damaged in the specimen, but they are not rudimentary (as in Nannobrachium), as they reach back to the root of the ventrals. The ventrals have five or six rays and reach back to the vent, but not so far as the anal; they are inserted nearly under the commencement of the dorsal, 12 m m . from the snout and 5 m m . behind the root of the pectorals. The anal begins behind the end of the dorsal and has about 7 rays; it is about as high as the dorsal, but its base is rather longer. Caudal forked. There are no spines on the tail above or below. The lateral line could not be made out. I am much indebted to the Rev. Padre Ernesto Schmitz for the single specimen of this little fish that has occurred. It was obtained from a fisherman. It was only ly9--- inch long, with a height of \ inch. When it came into m y hands it had been much injured, and it has therefore been impossible to speak positively as to some of the details. Perhaps it had been found in the stomach of another fish. However that may be, it had a deep-sea aspect. The following are the dimensions :- millim.

GONOSTOMA MADERENSE, sp. n. B. 11. P. 10. V. 8. A. 33. C. III.+ 19 +III. Elongate, compressed ; the height compared with the length minus the caudal fin being as 1 to 6i. Blackish, with two rows of silvery or pale steel-blue spots along each side of the belly. The specimen seems to have been clothed writh scales, but they have disappeared except from the head. The ridge of the back is rugosely warted, and apparently there have been no scales in that part. The head is to ^ihe length without the caudal as 1 to 5i. The top of the head is scaleless, and two low converging ridges meet in front of the orbits. The cheeks bear rather large scales. The opercular pieces are very thin and the gill-openings very wide. The profile is rather steep and the snout short. The round eye does not reach to the profile; its diameter is contained in the head about five times ; it is distant from the snout rather more than one diameter, and from the jaw rather less. The upper border of the mouth is formed partly of the premaxillary and partly of the maxillary, both being armed with teeth; the latter is dilated posteriorly. The |
