204 REPORT—1845. 
rays and valves of the sucking apparatus, which I have found however to vary as widely 
among individuals from the same locality, so that the ray-formula might be given as D, 2|33 to 
38; A. 2|32 to 38; Discal valves 23 to 26. A young Chinese specimen which was presented 
to the British Museum by Mr. Reeves, has the following numbers: Br. 9; D.2|38; C. 17; 
P. 21; V. 1|5; Discal valves 24. It agrees with a specimen of the same size in the same mu- 
seum which was captured at Tenasserim. Dr. Riippell observes, that the many individuals 
which he had an opportunity of observing in the Red sea presented constant differences in the 
numbers of the fin-rays and in colour from the Atlantic fish. In regard to the latter, I have 
stated above the variations of the rays that exist in the few specimens furnished by the museum 
at Haslar; and in respect to colour, I may add that the patterns they present appear to be 
infinite. Ihave seen on the western coast of Africa some hundreds attached to the bottom of 
a ship, and darting off in a dense body to partake of the washings of the cook’s coppers or any 
other greasy matter that was thrown overboard. All had, it is true, a very disagreeable- 
looking livid ground colour and a dark band on the cheek more or less extensively prolonged 
on the flanks, but the rest of the dark marks seemed to be alike in no two individuals. Spe- 
cimens 6 or 8 inches long have a trapezoidal caudal fin, but when they attain 18 inches or 
more the end of the fin is lunate, and the curve seemingly increases in older individuals, as it 
is pretty considerable in a specimen 24 feet long.

Forster, in his ‘ Faunula Sinensis,’ which comprehends the discoveries of 
preceding ichthyologists, enumerates only four members of this family, under 
the names of Gobius niger (Osbeck), G. eleotris, G. anguillaris, and G. pec- 
tinirostris (L.). These will be noticed under their respective heads.

This species belongs to a group of Gobies which have the depressed head and general 
aspect of Philypnus dormitator, and is very nearly allied to Gobius russelii (C. et V. 12. p. 75). 
It strongly resembles G. kokius, pl. 14. f. 1. of Jacquemont, Voy. dans |’Inde, which may be 
the same, #hough there are some differences. A specimen was presented to the British Mu- 
seum by John Reeves, Esq., and there are examples of it in the Chinese collection at Hyde 
Park and in the museum of the Cambridge Philosophical Society.

In Mr. Reeves’s drawing the back is mottled blackish-green, with clusters of grass-green 
and golden specks on the sides. The belly is grayish and silvery, the pectorals clay-coloured, 
the ventrals blackish-gray, and the vertical fins hair-brown, with two darker bars on the 
second dorsal.

A single specimen of a Goby, not in very good condition, exists in the museum of the 
Cambridge Philosophical Institution, having been brought from China by the Rev. George 
Vachell. It belongs to the group of kokius, but I have not been able to identify it with any 
of those described in the ‘ Histoire des Poissons.’ It has a depressed head with the eyes almost 
touching, an advancing lower jaw and a rounded caudal. Teeth setaceous, not crowded, 
and disposed much like those of a Serranus. The outer row on the lower jaw is composed of 
somewhat taller recurved ones. Four of the very short upper and under caudal rays appear
