as I can learn, of any Holothurian having been found in Co. Dublin, 

 especially as so many species of Holothui'ia have been found in Co. 

 Down.] 



"Vermes. — The following Platyhelminths have been met with : — 

 Planaria ulva, Oerst. ; Tetraste-mma dorsalis, Abildg. ; T. Candida, 0. F. 

 Miill. ; T. flavida, Ehren. ; Lineus marinus, Mont., and a species of 

 Amphiporus, which I believe to be new. All were found at Salthill. 

 Amphiporus laetifloreics, Johnst., is common at Malaliide. 



[Mr. Jacob dredged Carinella annulata, Mont., on June 6, 1885, in 

 Dalkey Sound.] 



Over two dozen species of Annelida have been collected and pre- 

 served. I am at present working at this group, and so refrain from 

 detailing my captures. The remarkable pelagic annelid, Tomopteris 

 seolopendra, Q,uoy and Gaim., once occurred in Kingstown Harbour 

 (August 26, 1883). Mr. E. Ball records that Bryarea seolopendra was 

 taken in Dublin Bay by Dr. Corrigan {Report Brit. Association, 1849, 

 p. 72). Prof. Allman captured some young specimens in 1873, on the 

 south coast of Ireland [Nature, ix., 1873, p, 74). Dr. E. Perceval 

 Wright has several times caught it on the south-west coast [Rep. Brit. 

 Assoc, 1860, p. 124), but this is a form which is widely distributed. 



\_Sayitta bipunctata, Krohn, was common at Kingstown in June, 

 1885.] 



I have two undetermined species of Phascolosoma, of which 1 

 made careful drawings. 



Most of the Polyzoa enumerated in the B. A. List have been 

 identified. I would here merely state that Pedicellina cernua, Pall. 

 (=P. ecliinata, Sards), is not at all rare at Salthill at extreme low 

 water, where the sessile form of Bowerlanlcia imhricata, Adams, also 

 occurs on Eucus. The only additions are Biastopora ohelia, (?) Johnst., 

 on Eucus at Salthill. Bowerlanlcia caudata, Hincks; Scrupocellaria 

 icrupea, Busk., and ^tea truncata, Landsb. 



I hope to procure the assistance of Prof. Herdman of Liverpool 

 with the local Ascidians, of which I have collected a number of forms. 



Mollusca. — The JN'udibranchs are the only Molluscs to which I 

 have any additions to make to the local list. I have met with the 

 following in Kingstown Harbour : Eolis drummondi, Thomp. ; E. lineata, 

 Loven. ; _£". despecta, Johnst. ; E. exiyua. Aid. and Hanc. — a variety of 

 E. exiyua of which I made the following note : — Similar in form and 

 habit, body translucent white, mottled with green along each side 

 below the branchise, one or two white dots about the insei-tion of the 

 dorsal tentacles; foot as in E. exiyua, but posterior extremity is long 

 and slender ; dorsal tentacles translucent, with one or two white dots 

 near apex ; branchiae, shape much as in E. exiyua, the yellowish 

 alimentary coeca shining through, irregularly spotted with green, tip 

 white. On Campanularia flexuosa, Kingstown Harbour, July 1, 1881. 

 Eolis sq. incert. This species, together with an Eolis from Dalkey 

 Island, I am witliolding for the present ; one or both may prove to be 

 new species. All the species of Eolis mentioned above are new to
