ACANTHOPTERYGII. 
agrees with the specific characters there attributed to that species, and 
generally with the detailed description of dimensions. So far as the brief 
description of colours in the Manual enables a judgment to be formed, 
there is a similarity between them. The specimen before me (preserved 
in spirits) presents considerable variety of colours. Two-thirds of the 
upper portion of the sides and entire body, from origin of anal to base of 
caudal fin, of a pale but rich brownish red, with faint indications of seve- 
ral transverse dusky bands ; remainder of anterior portion to ventral pro- 
file yellowish grey. Head variously coloured in stripes, &c., somewhat 
in the manner of Labrus variegatus, Gmel., and others of the Labridce ; 
iris bright red, lips orange ; dorsal fin pale, varied with red and dusky 
tints ; of this latter colour from the first to between the third and fourth 
rays ; a black spot, partly on the body and partly on the'base of the two 
last rays, terminating this fin ; pectorals reddish, with a black band at the 
outer base of the rays (similar to that in the variety of Crenilabrus Tinea 
called C. Cornubiensis ) ; ventrals pale, with reddish markings ; anal fin 
with faint dusky markings alternating ; caudal fin pale dusky, irregularly 
tinged with a reddish colour.

This individual has the ascending line of the pre-opercle less oblique 
than the smaller specimens ; the teeth, instead of the uniformity of ar- 
rangement described in C. multidentatus, increasing somewhat gradually 
in size towards the centre, 21 in the lower, and a similar number in the 
outer row of upper jaw ; a dark brown marking appears down the centre 
of many of them ; those of the other individuals are uniformly trans- 
parent. Scales three or four fewer in number on the lateral line in the 
large specimen than in the others, and the tubular projections on those 
throughout it less developed ; in it likewise the concentric strice of the 
scales are less strongly marked, and the lineated appearance (produced 
by the strice of each scale being more deeply cut along the centre than 
elsewhere) less apparent than in the others. The colour already described 
is very different from that of the smaller specimens. This individual, as 
well as those described as C. multidentatus, was obtained at Youghal. 
The Small-mouthed Wrasse, Crenilabrus microstoma, Couch, 
exoletus, Linn, (sp.), 
(See Yarrell’s British Fishes, vol. i. p. 341,) 
Has been taken on the North-East and West coast. 
In the month of June, 1836, a species of Crenilabrus was found on the 
beach of the County Antrim near Carnlough, by my friend Dr. J. L. 
Drummond, when engaged in collecting Algce, and, on his return to Bel- 
fast shortly afterwards, was kindly handed over to me. Being apparently 
undescribed, I at once drew up a minute account of it. When in London 
at the beginning of last summer, I ascertained that the same species had 
been met with in Cornwall by Mr. Couch, who likewise considered it as 
new, and sent two specimens to Mr. Yarrell, under the appropriate name 
of C. microstoma, a term which, although unpublished, I consider it but 
fair to adopt, as Mr. Couch had the priority in obtaining the species. 
Its most prominent characters are : — Body rather deep, mouth small, 
teeth few in number, and rounded or truncated at the summits : scales 
very large, those on the body concealing the base of the dorsal and anal
