THE HYDROID ZOOPHYTES. 107 



Great Ormes Head, at a depth of seven to eight fathoms, on 

 May 23rd, 1885, and was found at Colwyn Bay on June 

 13th, 1885, by Mr. Walker. 



It was dredged from fifteen fathoms at the Isle of Man, 

 off Port St. Mary, on August 3rd, 1885. 



It has also been found cast ashore on the sands at West 

 Kirby, opposite Hilbre Island. 



Family VII. — Haleciid-s:. 



Halecium halecinum, Linnaeus. 



Kecorded by Byerley as abundant. Mersey (J. S. Hicks). 

 Very common (A. 0. Walker). 



Dredged in Hilbre Swash on June 20th, from ten fathoms. 



Two large colonies, one male and the other female, both 

 with gonothecae, were dredged at Penmaenmawr, July, 1885. 



Five colonies, without gonothecae, and one female and 

 two male colonies, with gonothecae, were dredged off Port 

 Erin, Isle of Man, in August, 1885. 



In one of the male specimens from the Isle of Man, the 

 gonothecae are not " borne in rows on the upper side of the 

 pinnae ; " but are borne at the base of the calycles, as in 

 H. beanii. But in the latter species there is no pedicel to 

 the gonotheca ; while in our specimen a short pedicel of 

 about two rings is always present. In all other respects our 

 specimens agree with Hincks' description of H. halecinum, 



Hincks mentions in his Appendix a colony of H. beanii 

 dredged off the Isle of Man, which presents a curious modi- 

 fication of the gonothecae ; probably our abnormal specimen 

 is similarly only an unusual condition of H. halecinum, 



Halecium beanii, Johnston. 



Thoa beanii, Johnston, B. Z. (1st edit.) 120, pi. iii, figs. 1, 2. 



Mr. Walker states that this species is not uncommon in 

 the district, and he has also found the variety mentioned by 

 Hincks in his Appendix (p. 324).
