CYCLOSTOMI. 
The Fringed-lipped Lampern, or Planer’s Lamprey, 
Petromyzon Planeri , Bloch, 
Is found from North to South. 
The first examples which came under my notice were obtained by Dr. 
It. Ball, in 1836, from the neighbourhood of Naas, Co. of Kildare, as re- 
corded by me in the Zool. Proc., 1837, and also in the following notice 
which I contributed to the Annals Nat. Hist., vol. ii. : — 
“ Petromyzon Planeri, Cuv. Fringed-lipped Lamprey. — I am indebted to Dr. 
Ball for two specimens of this fish, which were obtained in the vicinity of Naas, 
County of Kildare. They are 4| and 5 inches in length respectively ; the smaller 
one only has the ‘anal sheath,’ which is 2 lines long. (See fig. in Yarr. B. F., 
vol. ii. p. 457.) The dentition in these specimens is similar to that shown in 
Mr. Yarrell’s figure of P. fluviatilis, and consequently in this character they do 
not accord with his figure of the mouth of P. Planeri ; in this same wood-cut, 
however, the chief peculiarity of the species — the fringed lip — is well represent- 
ed. The dentition, or ‘ armature of the mouth,’ of P. fluviatilis and P. Planeri , 
is similar, as remarked by Mr. Jenyns.* 
“ April 2, 1838. From the Rev. Charles Mayne, Vicar-General of Cashel — to 
whose kindness I have in several instances been indebted for specimens of .fishes, 
&c., from the river Shannon — I to-day received a lamprey, 4f inches in length, 
recently taken in the vicinity of Killaloe, and which proved to be the P. 
Planeri .” 
I have only to add that specimens have since been taken in some of 
the Northern Counties, and that this species is more common than P. 
fluviatilis. f 
The Pride, Sand Pride, or Mud Lamprey, Ammoccetes 
branchialis , Cuv., 
Is found from North to South of the island. 
The first native specimens of this fish which came under my notice were 
two sent me alive by Dr. It. Ball, in Jan., 1833, and referred to in the 
contribution which I made to the Zool. Proc. of that year. They were 
taken at Ballitore, County Kildare, where he first observed the species, 
under the circumstances mentioned in the following extract from a letter 
which I received from him shortly before the arrival of the specimens : — 
“ Ammoccetes branchialis. I have no specimen, but will endeavour to 
procure one. When at school at Ballitore, in 1817, and in pursuit of 
fresh-water cray-fish, I many times captured what we (boys) called 
‘ lamper eels ; ’ they were certainly not either of the species called 
lampreys, and I have no doubt of their having been the A. branchialis. 
They agreed precisely (so far as memory can serve) with the account in 
Fleming. They frequented mill-races and small streams, used to con- 
ceal themselves, when pursued, in mud or gravel, were generally seen 
under shelter of a stone from the current, maintaining themselves in 
constant vibratory motion in the same spot, I would almost say for weeks 
together, having known places where I was always certain of being able 
* Dublin, June, 1838. — Specimens of this lamprey have lately been received 
by Dr. Ball, from Inch river, about ten miles North-West of Youghal. 
f In a small stream running into the Blackstaff river, about two miles from 
Belfast, specimens of this species were captured in the spring of 1853, by Mr. 
Penrose Beale, of Belfast. These specimens were seen by us in a living 
state. — Ed.
