O. granulata (not very common, but remarkably large), Ophiothrix 
rosula (prodigious numbers), Asterias rubens, Cribrella oculata, 
Solaster papposa (very abundant, often of large size), Asterias 
gibbosa (not very common), Hchinus esculentus, H. miliaris (both

V. A New Species of Halcampa (H. Andres) from Malahide. 
By A. C. Haddon, Proc. R. Dub. Soe. (N.8.), iv. pp. 396-8, 
pl. xvi. figs. 1—4 (1885). 
Upon a subsequent examination of a number of individuals 
this species was withdrawn at the November meeting of the 
Royal Dublin Society of the same year (cf. Ann. and Mag. Nat. 
Hist. (5th ser.), xvi. (1885), p. 523, and infra), as it proved to be a 
variety of that extremely variable species, H. chrysanthellum, 
Gosse. It was first found in Ireland by Miss Shannon in 
September, 1883, at Malahide, Co. Dublin. 
VI. The Structure and Habits of Peachia hastata (Gosse). By 
A. C. Haddon and G. J. Dixon. Ibid., pp. 399—406, 
pl. xvi. figs. 5—8, and pl. xvii. xviii. (1885). 
This species was first found in Ireland (Dollymount, Dublin 
Bay) by Mr. Dixon, and exhibited by him before the Royal 
Dublin Society on Nov. 17th, 1884. The paper gives a full 
bibliography and a careful description with additional notes 
on the habits of this interesting form. The synonymy is 
Actinia cylindrica, Reid, and Siphonactinia hastata, Andres 
(Gosse sp.).
