ECHINODERMATA. 



Brissus lyrifer, Forbes, Brit. Echin. p. 187. 

 Of this species — discovered by Professor E. Forbes in the Clyde in 

 1840 — a few individuals were obtained off the south-west coast of 

 Ireland by Mr. MacAndrew. To use this gentleman's words, " One 

 or two specimens were brought up from a depth of forty fathoms off 

 Cork, and off Cape Clear, and from thirty fathoms in Bantry Bay, 

 near Great Bear Island. I have found it a frequent inhabitant of 

 muddy bottoms in from 12 to 100 fathoms." 



Holothuria. 



Since the publication of Forbes's ' History of British Echinoder- 

 mata,' a species of this genus as now limited (with normally twenty 

 tentacula) was noticed by Mr. Couch in the ' Cornish Fauna' (part 2. 

 p. 73) ; and another, believed by Mr. Peach to be distinct, has been 

 described and figured in the 'Annals,' vol. xv. p. 171. pi. 14. At 

 Tory Island, off the north-west coast of Donegal, Mr. Hyndraan 

 procured a specimen of this genus in a rock-pool between tide-marks 

 in August 1 845 . I abstain from naming the species even with doubt 

 in the present state of our knowledge of the Holothurice. 



Syrinx Harveii, Forbes, Brit. Echin. p. 249. 



Two specimens of a Syrinx were dredged in Strangford Lough 

 from a depth of fifteen to twenty fathoms on an oozy bottom in June 

 last by Mr. Hyndman and myself. They agree with the S. Harveii, 

 and at the same time with the S. granulosus, M'Coy (Annals, vol.xv. 

 p. 272. pi. 16. fig. 2), accordingly as they are viewed by the unas- 

 sisted eye or by magnifying power. The body of the former is de- 

 scribed as being " quite smooth," of the latter M nearly smooth, very 

 minutely and uniformly granulated ;" a difference which we might 

 expect to find between examples of 2^ and 7 inches in length ; these 

 being the respective dimensions of those described by Professor 

 Forbes and Mr. M'Coy. The body of my specimens — the larger of 

 which is under 2 inches in length — appears to the unassisted eye 

 not only quite smooth, but shining, though in a subdued tone ; yet, 

 when magnified, extremely minute papilla? are seen over its surface. 

 I therefore regard S. granulosus as not distinct from S. Harveii. The 

 figure of S. granulosus represents my specimens very well : they are 

 of a very pale grayish brown colour. 



Notes. 

 Cucumaria fusiformis, Forbes and Goodsir, Brit. Echin. p. 219. 



This species has already been enumerated in my Report on the 

 Invertebrata of Ireland, but no particulars respecting it have been 

 published. The specimen there alluded to, was dredged in ten
