The new Chetodon may be described as follows :— 
Cu&TODON picHRovuS. (Plate XVI.) 
D.5. A.=.  L. lat. 53. 
Snout rather produced, a little longer than the eye, with the upper 
profile concave; preeoperculum slightly serrated. Dorsal spines 
strong, the third and fourth the longest, two-thirds of the length of 
the head ; the soft portion of the dorsal and anal fins low, rounded. 
Body bicoloured—the anterior parts to the fourth dorsal spine and 
the lower half of the fish being uniform brown, the remainder (tail 
and caudal fins included) pinkish white. The scales of the lateral 
line silvery. 
There is only one example of this remarkable species in the col- 
lection ; it is 5 inches long. 
5. Further Contributions to the Ichthyology of Zanzibar. 
By Lieut.-Col. R. L. Poayrarr, H.B.M. Consul-General 
in Algeria. With a Note by Dr. A. Ginrunr. 
A large cask of fishes was lately sent to me by Dr. Kirk from Zan- 
zibar ; but, for want of adequate accommodation for examining so 
extensive a collection, I was compelled, after a single cursory in- 
spection, to close the cask again and send it to the British Museum. 
I, however, kept a few small specimens; and amongst these I find 
one new species, and two others which I had not before observed on 
the east coast of Africa. They are:— 
. ANTENNARIUS NIGROMACULATUS, sp. n. 
Divs 2s Ant ZeiPs 10; 
It is not without considerable reluctance that I venture to describe 
a new species of Antennarius with the limited means of identification 
at my disposal in Algeria; but this specimen differs so distinctly 
from all I have observed at Zanzibar and Seychelles, and from all 
that I can find recorded, that I am inclined to regard it as an unde- 
scribed species, 
Diagnosis.—Cleft of mouth subvertical and ascending in an oblique 
line, slightly inclined backwards. Length of maxillary bone one-
