ACANTHOPTERYGII. 
Ireland (on the shores of which country the species has not before been record- 
ed as met with), that the fish so named by Donovan, with which these were 
identical, is distinct from the G. niger of Pennant, and as such ranks as a third 
species of Gobius to the British Fauna, two species only having yet a place 
in it.” 
Mr. Yarrell afterwards applied to this fish the specific name of bipunc- 
tatus. 
This is a very handsome fish, not only from the blue markings along 
the side, and the large dark spots on sides of tail which give such an 
individuality to it, hut from the fins being delicately mottled with brown, 
or bronzed, and the dorsal having two or three light-coloured broadish lines 
throughout. The latter fins have much more beauty than Donovan re- 
presents. 
Owing to their dark colour, these gobies are everywhere conspicuous 
(in which they wholly differ from G. minutus, and the other species 
found in sandy bays), and seem unwilling to venture far from their fa- 
vourite fucus-covered rocks. Dr. Parnell’s observations on this species 
(p. 88) quite agree with the preceding, made previous to the publication 
of his work. 
As noticed in Charlesw. Mag., N. H., iii. 586, 1 obtained specimens from 
Portpatrick, through the kindness of Captain Fayrer, R. N. 
Sept. 16, ’35. — I remarked that this species was now much scarcer in 
the rock-pools in Ballyhome Bay, than I have found it there in winter. 
June 22, ’46. — A Gobius bipunctatus was found in a common tern shot 
to-day on Laithe Rock, Strangford Lough. 
Mr. Yarrell’s collection contains specimens similar to mine, which were 
taken by him in Poole Harbour. 
The Freckled Goby, Gobius minutus , Pall., 
Is common on sandy shores, where it is found with the next two species, 
from North to South of the island. 
I have seen specimens taken in various localities from the County of 
Antrim, along the eastern line of coast to Cork, inclusive, and Mr. 
M‘Calla noted it as common on the coast of Galway. 
Immature specimens I have found in abundance in sandy pools on dif- 
ferent parts of the coast of Down, and I have obtained larger ones — 3 
inches long — by dredging in water several fathoms deep. 
Templeton noticed the species in his catalogue thus : — “ Several speci- 
mens, but not of greater length than 2 inches ; stated to be common 
on the sandy shores, lodging under large shells when the tide is out.” 
I have seen this species display the rosy tint in the D. fin noticed by 
M‘Coy in Annals Nat. Hist., vol. vi. p. 404, and in other characters so 
closely agreeing with the specimen there described, and considered to be 
Gobius reticulatus , Cuv. and Val., that I cannot consider them to be of 
two species. 
The Slender Goby, Gobius gracilis , Jenyns, 
Is found from North to South. 
The subjoined notes upon this fish have been already published 
by me : — 
“ From the coasts of Down and Louth I have obtained two specimens of this 
fish. The difference in colour between them and Gob. minutus attracted me at 
first sight ; but I did not examine further, until my attention was directed to
