THE BI MACULATED SUCKER.

“Notwithstanding the existence of these and some other points of minor differ- 
ence between the specimens in question and the C. bimaculatus, as described, 
I conceive, from their agreement in other characters and in economy, that they 
are of one species. 
“ In length these specimens are respectively 1 inch 10 lines, and 1 inch 5 lines. 
The former has 5 rays in the dorsal, about 18 in the pectoral, 4 in the ventral, 
and about 12 in the caudal fins. The latter has a similar number in the dorsal, 
pectoral, and ventral, but the caudal presents at least 13, and the anal (owing 
possibly to its being injured) only 3. 
“ The prevailing colour of the larger fish is pale 4 reddish orange,’ that of the 
smaller dark reddish orange, in both specimens varied with round spots and 
irregular markings of white ; the latter also exhibits large blotches of pale 
vermillion along its back. In both, the belly and organ of adhesion are yel- 
lowish. 
“These specimens agreed with Montagu’s observations on the C. bimaculatus 
by 4 instantly attaching themselves to the hand when taken out of the water,’ 
and by 4 preserving their beautiful pink colour in spirits, ’ or I should rather 
say simply of preserving their colour, as, although differing in this respect, they 
have retained their original brightness unimpaired. 
44 Besides the above differences, there is not any other observable between these 
fishes and the descriptions and figures of the C. bimaculatus in the works quoted 
that seems to demand attention.” 
I was pleased to find, on the subsequent publication of Mr. Templeton’s 
Catalogue, that this species was known to him. He notes 44 two specimens 
found in a dredge, August, 1811.” By subsequent deep dredging in Bel- 
fast Bay and Strangford Lough, specimens have been obtained. On one 
occasion I took upwards of a dozen specimens of this fish at the former 
locality, on some of which the spots were wanting. The species is noted 
in the Ord. Surv. as 44 from Larne.” 
Mr. Hyndman, when dredging (20th June, 1844) off St. John’s Point, 
County of Down, brought up from a depth of fifteen fathoms, a perfect 
and full-grown specimen of the bivalve shell, Venus virginea, in which 
were a L. bimaculatus, with its ova and young, some only of which had 
made their appearance ; and the same gentleman, at the end of August in 
the same year, dredged in Belfast Bay a single full-grown valve of Pectun- 
culus pilosus, the hollow of which was close studded over for the space of 
a square inch with the ova of this species, each ovum touching or close to 
the next one. These ova are deposited singly over the surface of the shell on 
which every one rests, each ovum globular, about 1-1 6th of an inch in dia- 
meter, which is remarkably large for a species which I have not known to 
exceed 2 inches in length. 
I had frequently seen this species when brought up in the dredge with- 
in old single valves of bivalve shells, but until the instances just men- 
tioned occurred I was not aware of the cause of its partiality to them. 
March 30, 1846. A specimen about 2 inches long was brought to me 
alive in Belfast market, having been found among Killinchy oysters 
(probably taken from the water twenty-four hours before). The whole 
upper surface of the living fish was of a dark purplish brown colour, with 
minute yellow spots disposed over it : the under surface was whitish flesh 
colour, but pinkish with darker spots of red in the hollow portion to- 
wards sucker. 
Eye proper dark blue with brilliant orange irides. 
April, 1846. After being in spirits for some little time, this specimen is 
of the usual red colour on the upper surface. 
In 1839, I saw in Dr. Ball’s collection a specimen dredged by him off
