320 Wright— For aminif era of Down and Antrim. 
(Balk will and Wright). It has also been recorded from two of the “ Challen- 
ger ” o-atherings— viz., off Christmas Harbour, Kerguelin Island, 120 fathoms, 
and Station 238, in the very deepest part of the Pacific, 3950 fathoms * It is 
indeed remarkable that a species which, in this climate, has been only met 
with in shallow water and shore gatherings should, in the North Pacific, occur 
at such a great depth. 
Placopsilina cenomana, D'Orbigny. (Pl. xxvi. fig. 3, a, b.) 
Placopsilina cenoviana, d’Orbigny, 1850, Prodr. Paleont., Vol. II., p. 185, 
No. 758. 
One large specimen of this rare species was found by Dr. Malcomson at 
Rockport, between tides. The specimen figured is the only example which 
has been obtained in Britain. 
Verneuilina polystropha, Reuss,sp. (Dimorphous form. PI. xxvi. fig. 2.) 
Bulimina polystropha, Reuss, 1845, Yerstein. Bbhm. Kreid., part 2, 
p. 109, pl. 22, fig. 53. 
This species is of frequent occurrence around our coast. An abnormal 
form, in which the later chambers are arranged in a linear series, with a 
simple round aperture, is occasionally met with in shallow water gatherings. 
Mr. Brady considers it a dimorphous form of Verneuilina polystropha. 
Spiroplecta biformis, Parker and Jones, sp. 
Textularia agglutinans var. biformis, Parker and Jones, 1864, Phil. 
Trans., Yol. civ., p. 370, pl. 15, figs. 23, 24. 
A few years ago this species was found for the first time in British watei 
by Dr. Malcomson, who obtained several good typical specimens at Rockport. f 
A few specimens have since been found in Dublin Bay (Balkwill and Wright). 
Lagena semilineata, Nov. sp. (Pl. xxvi. fig. 7.) 
Test flask-shaped, with a long, ectosolenian neck, the lower extremity 
furnished with a short projecting neck ; upper portion of the body of the shel 
usually smooth ; lower portion ornamented with very numerous, closely-set, 
longitudinal sulci ; neck marked with longitudinal lines, which occasionally 
extend a little way down the shell. . . 
This very elegant form may be readily distinguished from L. semistnata 
by the ornament on the lower portion being closely-set, longitudinal sulci, 
instead of the strong costate ribs of the latter species. It has been found at 
only a few localities, and is rare where it occurs.
