8 Prot. 
PROTOZOA. 
Pleurophrys in having the shell composed of a coarse calcareous network ; 
salt-pan. 
Pleurophrys helix^ Entz (8), p. 186, pi. ix. figs. 1-4 ; salt-pan. 
Quadrula irregularis^ Archer (1 a), p. 113 ; various localities. 
Noctilucina. 
Leptodiscus, Hertwig (12), p. 307, pis. xvii. & xviii. L. medusoides. 
Differs from Noctiluca in its normally placentoid form ; also in double 
character of nucleus, and unstriped flagellum ; Messina. 
Fossil Khizopoda. 
New Genera. 
Ascodictyon* Nicholson & Etheridge (19), p. 463, pi. xix. A. fusi- 
forme, stellatum^ and radians^ spp. nn. Composed of calcareous cells, 
with minute foramina ; no large aperture ; colls united by tubes of 
varying dimensions. 
Schioagerinay Moller (18), p. 143. Like Fusulina, except in the non- 
plicated character of the outer part of septum (based on Borelis sphce- 
roidea, Borel). 
.HemifusuUna, id. 1. c. p. 144. Like Fustdina, but septum is two- 
layered, producing grooves on surface. (1 sp.) Twer, near Prjamuchina; 
Carboniferous limestone. 
Fusinella, id. ibid. fig. p. 145. Differs from Fusulina in the slightness 
of the plication and the thickness of septa, which carry canals and a 
“ supplemental skeleton.” (1 sp.) Near Twer ; Carboniferous limestone. 
Kemarks on Fossil Forms, Distribution, &c, 
Parkeria rejected by Carter (7) from the Foraminifera^ owing to its 
large foreign nucleus, and compared with Hydractinia. He distinguishes 
3 species. 
Loftasia persica, Br., considered (7) as also akin to Hydractinia^ rather 
than to the Foraminifera. Zittel (^Spongida, 18) supports these 
opinions. 
Stromatopora (7) also agrees strikingly with Hydractinia in its minute 
fibre-characters, &c. 
A list of genera and species, with the formations, <§:c., of America, is 
given in “ The American Palaeozoic Fossils,” by S. A. Miller (Cincinnati, 
Ohio : 1877). 
A supplementary note on the Foraminifera of the chalk of the New 
Britain group, by H. B. Brady, Geol. Mag. iv. p. 534, gives a list of 
species, including a Glohigerina, sp. n., and Pulvinulina^ sp. n. 
Wehhina, D’Orb. Sollas (22) proposes to restrict this name to (he 
perforate forms (which he, for the first time, shows to exist) leaving the 
rest to Trochammina. He describes 2 new species. 
* The authors are uncertain whether it is Foraminiferous, Sertularian, or 
Polyzoan in affinities.— S. O. E.
