266 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. 

 E.. Ball, in 1836, from the neighbourhood of Naas, Co. of Kildare, as re- 

 corded by me in the Zool. Proc, 1S37, 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. fuviatilis, 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. Jiuviatilis 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, 4| 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. 

 Jiuviatilis. t 



The Pride, Sand Pride, or Mud Lamprey, Ammocoetes 

 hranchialis, 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. II. 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 befoi'e the arrival of the specimens : — 



" Ammocoetes hrancldalis. 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. hranchialis. 

 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, aboiit ten miles North-West of Youghal. 



t In a small stream running into the Blackstati" 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.
