without serratures, a single row in the lower, and two rows in the 

 upper jaw ; scales very large, those of the body concealing the base 

 of the dorsal and anal fins, but none apparent on the fins ; anal fins 

 with six spinous rays, ventral scale half the length of ventral fin ; 

 pre-opercle strongly denticulated.

* Crenilabrus 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. Ball. As in the instance of the last 

 noticed, I cannot by careful research find any species described with 

 which they agree, I, though with hesitation, bring them forward as 

 new, under the name of Cren. multidentatus. The specimen from 

 which the description has been drawn up is 2\ inches in length. Its 

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

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

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

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

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

 chiostegous membrane five rays. 



D. 19 + 10; A. 3+8 ; P. 14 ; V. 1 + 5 ; C. 13, well developed. 



* Abramis Buggenhagii. Large-scaled Bream. Cyprinus Buggen- 

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

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

 tected a bream difli^ering from the common species, and secured it for 

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

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

 consisting in the number of rays in the pectoral fin, 12 being enume- 

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

 however, 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, 1^ 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 lateral 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 anal 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 lakes 

 communicating with it *. 



* On my showing this specimen to Mr. Yarrell, he immediately produced 

 from his own collection another example of this species of much larger size, 

 measuring fourteen inches in length, which had been presented to liim by a
