Mr. Thompson's Additions to the Fauna of Ireland. 247 



Ophiura granulata, Flera. Brit. Anim. Coast of Dublin (R. Ball) 

 and Down (W. T.). The species figured by Templeton (Mag. 

 Nat. Hist. ix. 237.) with doubt as this species is the 0. rosula. 



Ophiocoma brachiata. 



Asterias brachiata, Mont. Linn. Trans, vol. vii. p. 84. Of this species, 

 apparently known only to Montagu, two specimens were ob- 

 tained in August 1836, by Mr. Hyndman and myself, when 

 dredging off Dundrum on the coast of Down : the body of the 

 more perfect one is ^rd of an inch in diameter, the least in- 

 jured arm 3-|- inches long, and w r here broken nearly as broad as 

 at the base. 



Ophiocoma minuta, Forbes. This Ophiocoma as distinguished by 

 Mr. Forbes from Op. rosula (Wern. Mem. vol. viii.) has oc- 

 curred to me in the north ; and among marine productions from 

 Courtmasherry harbour (county Cork) favoured me by Mr. All- 

 man is a fine specimen. Templeton has noted the 0. minuta of 

 Pennant as Irish, but its identity with the present species is 

 doubtful . 



Holothuria pentactes, Mull. Z. D. vol. iii. p. 47. t. 108. f. 1 — 4? 

 Among a quantity of marine productions dredged in Belfast bay 

 in October last by my friend Edmund Getty, Esq., and kindly 

 sent to me, was an injured specimen two inches in length, ap- 

 parently of this Holothuria. 



Mulleria* papillosa, Johnst. Mag. Nat. Hist. vol. vii. p. 584. f. 66. 

 Dredged in Belfast and Strangford loughs in 1834, and subse- 

 quently by Mr. Hyndman and myself. 



Cuvieria phantapus, Flem. Johnst. Mag. Nat. Hist. vol. ix. p. 472. 

 f. 68. 



Holothuria phantapus, Mull. Z. D. vol. iii. p. 54. pi. 112. In Sep- 

 tember 1835 I obtained by the dredge a single specimen at 

 Bangor, county of Down. 



Vermes. 



Planaria tremellaris, Mull. Zool. Dan. t. 32. f. i, 2. At the end of 

 April I have taken numbers of this species from the under sides 

 of stones in pools among the rocks at Rockport, Belfast bay. 

 The specimens were rather under the size — " long. 9 lin. lat. 

 4 lin." — attributed to the species by Muller, but were other- 

 wise identical. 



Planaria vittata, Mont. Linn. Trans, vol. xi. p. 25. tab. 5. f. 3. A
