 Mr. Busk gives no further locality for this species than 

 " Hab. Britain (North ?)." I have dredged it off" the North- 

 umberland coast and Shetland, and have received it from 

 Scarborough (Bean) and Aberdeenshire (Dawson). Smitt 

 records it from Bahusia and Spitzbergen. 



Menipea Jeffreysii, n. sp. PI. V, figs. 3 — 5. 



Polyzoary dichotomously branched. Cells 4 — 7, at an in- 

 ternode, elongated below; apertures regularly oval, margin 

 a little raised, above three (or four) spines -, on the outer 

 angle of each cell is a small process, probably the base of a 

 larger spine, which has been broken off"; a small avicularium 

 in front of each cell beneath the mouth ; mouth furnished 

 with an operculum, which is entire. Ovicell erect, smooth. 



A minute portion of this species was found by Mr. Peach 

 among sand dredged in Shetland in 1864, and two other still 

 more microscopic fragments were found by him in sand 

 dredged by Mr. Jeffi-eys and myself in Shetland in 1865. 

 These fragments are amply sufllcient to show that we have 

 a new species in them, but not sufficient to enable the cha- 

 racters to be accurately defined. In every cell except one 

 the operculum is broken off"; that one Mr. Alder has, in the 

 figure he kindly drew for me, represented as lobed, but the 

 operculum was dirty at the time, and having since cleansed 

 it, I find it to be entire, and that what appeared to be divi- 

 sions were surface markings only. 



At Mr. Peach's request, I have dedicated the species to 

 my friend Mr. Jeffi'eys, with whom I have spent so many 

 a happy hour in examining the Fauna of our seas. 



This species approaches, in its general characters, to the 

 Arctic Menipea which is figured by Smitt, in his recently 

 published papers on Scandinavian Polyzoa, as Cellularia
