NORTHUMBERLAND AND DURHAM. 103 



these two forms of Coryne^ I have obtained, at dififerent times, 

 another form, apparently a species (PI. IX., fig. 1, 2) on old 

 crusted shells of Fusus antiqmis, from deep water, at Cullcrcoats. 

 Should it prove distinct, I would propose for it the name of 

 Coryne pelagica. Very short horny tubes rise at intervals from a 

 creeping stem, and are sharply annnlated by ridges of growth ; 

 the last formed portion springing from within the other in a cup- 

 like form. The polypes are much elongated, and nearly cylin- 

 drical, swelling a little at the end, with the tentacles numerous 

 and very short, set in seven or eight imperfect rows. Height 

 scarcely the tenth of an inch. This is perhaps the Coryne pusilla, 

 var. y of Lieut. Thomas (Johns. Brit. Zooph., 467), of which he 

 says, " y deep sea ; heads pink, subcylindrical — Yorkshire. 

 The polypidom of this species closely resembles the creeping 

 variety of C. dumosa^ This form also comes near to the Coryne 

 sessilis of Gosse (Devon. Coast. 208, t. xiv, f. 1 — 3), but it differs 

 in the shortness of the arms, and in the character of the horny 

 tube. Mr. Gosse obtained his species within tide-marks.

 Tulularia ramosa^ ibid, in Newc. N. H. Trans, v. 2, 253, t. 10. 

 Not unfrequently brought in on the fishing lines at Culler- 

 coats and Whitburn; also got from the five-men boats. 

 According to Sir John Dalyell the reproductive capsules of 

 this species are of two kinds (probably sperm and ovicapsules). 

 Those I have met with form a cluster round the base of the ten- 

 tacles, and are arranged in a linear or moniliforai series, two or 

 three on each pedicle.
