154 ^'^'^ Irish Nattiralist. ' July, 



from which the animal is here described, and the drawings made, is a 

 female, which apparently differs in no respect from the male except 

 in sex, was procured by the ' Porcupine ' Expedition in 1869 in the 

 Atlantic, west of Donegal Bay, Ireland, Stat. 20, lat. 55<* 11' N., long. 

 11° 31' W., in 1,443 fathoms, bottom temperature 37° Fahr. It is 

 interesting to observe that though the specimens were found so 

 very far apart the temperature of the water only differed by i^ degrees, 

 since 2" C. equals 35*^ 6' Fahr." Owing to the great uniformity of 

 temperature in the great depths of the oceans, I believe that it will 

 be found generall)', as expeiience is gained, that the deep water 

 species have a much wider distribution than those which inhabit 

 depths subject to alteration of temperature dependent upon 

 atmospheric conditions. 



Genus 2.— Phlloinedos, Lilljeborg. 



Phllomedes Interpuncta (Baird).— Valentia, 1870, and Birturbuy 

 Bay (A.M.N.) ; off White Head, Belfast Lough, 19 fathoms (vS.M.M.). 



P. MacAndrel (Baird).~Taken by the " Porcupine," 1869, at two 

 stations off the south-west of Ireland, viz.. Stations 3 and 7, in depths 

 of 722 and 159 fathoms; and also at Station 18, off Mayo, in 

 183 fathoms. 



Fam. 3.— SARSIELLIDiC. 

 Genus. — Sarslella, Norman. 



Sarslella capsu la, Norman.— The form we described in our monograph 

 as Neniaiohamma obliqua is. according to +he observations of Herr 

 G. W. Miiller, who has found the genus Sarsiella to be not uncommon 

 at Naples, the male of Sarsiella capsula. Both sexes were dredged by 

 me in 1870, in 112 fathoms, off Valentia, and the male also off 

 Birturbuy Bay. 



Fam. 4.— HALOCYPRID.«. . . .\ 



Genus i.— Conclioecia, Dana. 

 Conchoecia Haddoni, Brady and Norman.— Captured by Professor 



Haddon in a townet sunk to 200 fathoms, 40 miles off Achill Head. 



These are the types. 

 C. magna, Claus.—" Oceana," Station 1,1 270 fathoms; Station 4, 



150 fathoms. 



1 The " Oceana " had four days townetting in very deep water ; the first 

 and fourth of these were within the British area, and I shall term them 

 Stations i and 4. See Brady, Aun. ^ Mag. Nat. Hist. (7) vol. iii., 1903. 



P- 337- . . ., 



Station I Lat. 52" 4-5' N., long. 12° 27' W., in 270 to 650 fathoms. 

 Station IV. Lat. 52° 20' N., long, is'' 79' W., 150-560 fathoms. The 



remaining days were spent working over depths beyond 1,500 fathoms,
