* Crenilahrus multidentatus. Ball's Wrasse. Three specimens of a 

 Crenilabrus, taken at Youghal in the summer of 1835, have been 

 sent me for examination by Mr. Bali. As in the instance of the lašt 

 noticed, I cannot by careful research tiud any species deseribed with 

 Avhich they agree, I, though \vith hesitation, bring thera for\vard as 

 ne\v, under the name of Cren. multidentatus. The specimen irom. 

 which the description has been dra'vvn up is 2^ inches in length. Its 

 chief characters are, — form elongated, mouth large and povverfuUy 

 armed, upper jaw the longer, pre-opercle slightly denticulated, scales 

 of moderate size, ventral scale one-fourlh the length of ventral fin ; 

 a blackish spot behind the eye, another at the base of the lašt ray of 

 the dorsal fin, and a third at the lowermost portion of the tail, bran- 

 chiostegous membrane five rays.

* Ahramis Buggenhagii. Large-scaled Bream. Cyprinvs Buggen- 

 hagii, Bloch. Part 3, tab. 95. On inspecting the produce of a fishing- 

 rod at theriver Lagan, near Belfast, on the 6th of May, 1836, I de- 

 teeted a bream diiFering from the common species, and secured it for 

 examination. It agreed so fuUy with Bloch's description of the Cy- 

 prinus Buggenhagii as to satisfy me of its identity, the only difference 

 consisting inthe numberof rays in the pectoral fin, 12 being enume- 

 rated by him, and 18 appearing in the specimen ; several of them, 

 hovvever, being very short, may have escaped Bloch's notice. 



The description drawn up from my specimen the day it was pro- 

 cured, is as follows : Length, 5| inches ; depth, lį inch; head one 

 fourth of the entire length ; diameter of the eye equal to one fourth 

 of the length of the head ; scales on the laterad line about 45, about 

 9 rows between it and the dorsal ridge and 5 rows below it ; under 

 point of the caudal fin longer than the upper. Colour of the sides 

 silvery, tinged with blue towards the back ; irides very pale yellow ; 

 the dorsal, pectoral, ventral, and anai fins nearly transparent, or very 

 slightly tinged with dusky, chiefly towards their extremities ; cau- 

 dal fin pale yellow. 



D. 11 ; P. 18 ; V. 1 + 9 ; A. 20 (first extremely short) ; C. 18. 



This species, which is new to Britain, is stated by Bloch to be 

 found in Swedish Pomerania, in the river Pene, and in the lakęs 

 communicating \vith it *. 



* On ni}' showing this specimen to Mr. Yarrell, he immediately produced 

 from his owii collection another esampleof this species of mucli larger size, 

 measuring fom-teen inches in length, which had been presented to him by a
