MALACOPTERYGII. 
another stomach afforded the Amphidesma Boysii of large size, a specimen 
of Dentalium, and a few specimens of Amphidesma prismatica ; after a like 
interval the stomachs of three or four individuals were well supplied with 
beautiful specimens of Amphidesma prismatica , Nucula tenuis, a small 
Anomia, Amphidesma Lysteri (small size). Lens of fish eye. Donax trunculus, 
but in the latter examinations of about a dozen altogether, at different 
times, all shells have disappeared with the exception of the Amphidesma 
prismatica, and that sparingly ; the stomach was filled with a green 
vegetable substance, and in the last stomach which I examined, I found 
two specimens of the Trochus umbilicatus. 
“ It is worthy of remark that after October I did not obtain a single spe- 
cimen of Cardium elongatum or Amphidesma Boysii, and that, although 
all the specimens were evidently recent, having the epidermis very per- 
fect, nevertheless, with the exception of Nucula Tenuis and Trochus cine- 
reus the shells were all empty.” 
The Lemon Sole, Solea Pegusa, Yarrell. 
A specimen of this fish was obtained by Mr. W. Todhunter on the Gal- 
way coast in 1848. 
It is now in the Dublin University Museum. 
In the 2nd edition of his Br. Fishes, Mr. Yarrell inadvertently men- 
tions this fish as Irish in connexion with my name. It had not then, so 
far as I am informed, been met with on the Irish coast. 
Specimens sent to Dr. Ball. Length 10 inches; breadth of body, ex- 
clusive of fins, 44 inches. Papillary eminences numerous on under side 
of head, less so than in the Solea vulgaris. “Very many specimens were 
obtained” by Mr. Todhunter, but the exact locality not mentioned. 
Three specimens were sent from County Galway, Sept. 7th, 1848, by Mr. 
Todhunter to Dr. Ball; the largest was 12 inches in length; the skin 
only preserved ; it was taken at Bunowen. 
The Solenette or Little Sole, Solea Lingula, Rond., 
Monochirus linguatulus, Cuv., 
Has been obtained on the North-East, East, South, and West coasts. 
The following notices of this species were contributed by me to the 
Annals Nat. Hist. vol. ii. 
“ Solea Lingula, Rond.,* Red-backed Sole. — On the 23rd of August, 1836, 
three small specimens of this fish were captured by Mr. Hyndman and myself 
when dredging on a sandy bottom off Dundrum, in the County of Down.

Breadth of body of No. 1, 13 lines. In form they differ considerably from Solea 
vulgaris, by tapering towards the tail. Dorsal and anal fins similarly connected 
with the caudal, the last ray of each exhibiting a low inconspicuous membrane, 
which extends to the base of the outer caudal ray — these three fins, merely 
touching in this manner, appear at a cursory view unconnected, In the number 
of rays in the fins, and characters generally, they correspond with Donovan’s 
* Solea parva sive Lingula, Rondeletius ; see his figure of “ la petite sole,” p. 
260; also Willughby’s figure and description, p. 102, F. 8, fig. 1.
