DESCRIPTION OF A NEW FISH FROM LORD HOWE 
ISLAND. 
By J. Douglas Ogilby. 
Tetrodon altipinnis, sp. noi \ 
D. 10. A. 8. P. 16. C. 8. 
The length of the head is three and three-fourths in that of the 
body. The eyes are situated at an equal distance from the tip of 
the snout and the upper pectoral ray, and the diameter is two- 
thirds of the length of the snout : interorbital space slightly con- 
cave, three-fifths of the diameter of the eye. Nasal openings two 
on each side placed in a moderately prominent papilla. Dorsal 
profile of moderate breadth and very slightly concave. The 
distance between the tip of the snout and the origin of the dorsal 
fin is one and six-sevenths in the total length : the snout is five- 
sevenths of the distance between the posterior dorsal ray and the 
origin of the caudal fin, and is rather longer than the height of 
the caudal pedicle immediately behind the anal fin, the greater 
portion of which is situated behind the dorsal : both dorsal and 
anal fins are high and falcate, the second or highest ray of the 
former being two and a half times the height of the last ray, while 
in the latter there is a corresponding difference though in a lesser 
degree : the pectoral fins are short, rounded, and but slightly 
longer than the snout : the caudal is long, five-sixths of the length 
of the head, and truncate with the outer rays produced. No 
lateral fold on the tail. The upper surface of the head, the light 
coloured part of the sides, and the under surface of the body with 
acute scattered spines; anterior moiety of the dorsal profile covered 
with densely crowded sinuous rugosities, and with a few irregu- 
larly placed smaller spines j rest of the back and the tail, above 
and below, with similar rugosities, but spineless. Colors — The 
upper surface of the head yellowish-brown, the lips and sides of 
the head much darker ; the back and upper half of the sides gray, 
ornamented with numerous milk-white spots, a few of which have 
a dark centre ; lower half of sides, entire under surface, and fins 
bright yellow. 
The species above described was brought from Lord Howe 
Island by Mr. Icely, the Visiting Magistrate, and measures nine 
inches in length. 
To the under jaw of this specimen there was attached a Cirri - 
peel belonging or allied to the genus Anelasma , possessing ramose 
appendages near the base of the peduncle. The cirrhi are however 
fully developed, and not rudimentary as in Anelasma squalicola , 
of Loven. This specimen has been examined by Mr. Brazier, who 
tells me that it is quite unknown to him and will probably turn 
out to be a new species. Should such, on future investigation, 
prove to be the case, a description from Mr. Brazier’s pen will 
probably appear in “ The Records ” in due time.
