132 ACANTHOPTEKYGII. 



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 Lahriis vai'ier/atiis, Gmel., and others of the LabridcB ; 

 iris bright red, lips orange ; dorsal fin pale, varied Avith 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 Crenilabrxis 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-operclc less oblique 

 than the smaller specimens ; the teeth, instead of the uniformity of ar- 

 rangement described in C. mnltidentatiis, 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 

 lavge 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 sti'ongly marked, and the lineated appearance (produced 

 by the strics 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 sjjecimens. This individual, as 

 well as those described as C. multidentatus, was obtained at Youghal. 



The Small-moutiied Wrasse, Crenilahnts microstoma, Couch, 



exokfus, 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 Crenilahrus was found on the 

 beach of the County Antrim near Carnlough, by my friend Dr. J. L. 

 Drummond, when engaged in collecting Ahjcp., 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 Mhich, 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
