xvii. p. 140; Q. J. Micr. Sc. xii. p. 413. 
0. Schmidt’s paper on Coccolitlis and Rhabdolitlis (c/. Zool. Rec. viii. 
p. 489) is translated in Ann. N. II. (4) x. pp. 359-370, pis. 10 & 17. 
Whiteaves mentions shortly the Foraminifera and Poh/ct/siina found hy 
deep-sea dredging in the Gulf of St. Lawrence : Ann. N. 11. (4) x. pp. 343 
& 344. Greeff (‘ Madeira,’ p. 33) refers to those of the Canaries, and 
Metzger (supra p. 421) adds a few species to the list of the Forainmifera of 
the East-Friesland coast, p. 15. The mud bottom of the innermost parts 
of Ilardangerfjord, at 500 fathoms, according to G. O. Sars (Forh. Selsk. Chr. 
1871, p. 250), is filled with an enormous number of brownish bodies, of the 
shape and size of small hail-stones (Saccammina sph,a>ricn, Sars, MS.). In 
their company long radiating stems of a light brownish colour (Rhahdammina 
ftb(/sso7-um, Sars, MS.) and some rhizopodous organisms, very like Annelidnn 
tubes (liathi/siphon filiformis), wore found : 13 other species of Wiizopoda 
and Sponyozoa are enumerated from this deposit. Archer shortl}^ mentions 
various Irish freshwater Rhizopoda, FJng<dlnta, &c. : Q. .1. IMicr. Sc. xii. 
F. Stuart, Z. wiss. Zool. xxii. p. 200, .shortly describes the gommiparons 
propagation of CoUozoum merme. 
Blaster greeffi, g. & sp. nn., Grimm (4), in peat-swamps at Novgorod. A 
globular mass of finely granular protoplasm, enclosed in a fenestrate sili- 
ceous shell and including a central capsule, from which delicate lines radiate 
towards the periphery, probably axial cylinders of the numerous delicate 
pseudopodia radiating from the surface of the ball. 
Myxohrachia cienkoicskti, sp. n., Wagner (0), Naples. No proper body- 
walls, only a partial covering of confluent filaments, from which numerous 
p.seudopodia emanate, the body not being formed of a gelatinous homo- 
geneous mass, but of a felt of delicate protoplasmic threads, between which 
delicate cytodes are bnbedded. Coccolitlis, coccosphores, shells of young 
Rivalvia^ SpiruUna, &c. were found imbedded in the extremities of the arms. 
Thalassicolla cienJcotvskii, sp. n., Wagner, 1. c. 
Traquairia, g. n., Carruthers, Q. J. Micr. Sc. xii. pp. 397 & 398. A radio- 
larian Rhizopod from the Coal-measures. 
Pelohius, Greetf (nec Schonh., Col.), Zool. Rec. vii. p. 617 : changed to 
Pelonigxa. Greef, SB. Ges. Marb. 1872, p. 169. 
Fhrenrerg (I) gives an historical and systematic review of the Ai-- 
celUntje, which are distributed as follows : — 
1. Arcella. Loricce apertura lateral! aut medio-infera, pseupodio sim- 
plici aut multiplici, piano aut filiformi. 
1. Hoinceochlamys* , Lorica inermis, suborbicularis aut oblonga, IjBvis aut 
subtiliter sine ordine punctata, aut nebuloso-maculata, interdum costata : 
a, orbiculares, 6 spp. ; h, oblongae, 10 spp. 
2. Sticholcpis* . Lorica inermis, orbicularis aut oblonga, areolarum aut 
assularum seriebus ornata : a, orbiculares, 3 spp, ; h, oblougno, 5 spp. 
3. Ceniropyxis,. St. Lorica varia, aculeata aut setosa : 3 spp. 
4. Heterocosmia*' Lorica inermis, superficie areolis sine ordine coelata, 
suborbicularis aut oblonga : a, orbiculares, 4 spp. ; h, oblonga?, 4 spp. 
* These divisions, and those similarly marked on p. 484, are apparently 
new, so far as can be judged from Ehrenberg’s paper.
