The following species of Appendieularia and allied genera have been ob- 
served by H. Fol in the Straits of Messina, and described accurately : — 
1. (Ecopleura (Chamisso). Body short and thick; endostyle straight; 
tail 3-4^ times as long as the body ; no hood (capuchon). copliocerca 
(Gegenbaur), spissay rufescmsy dtoaca (c? & $), fundi fmiformisy spp. nn., 1. c. 
pp. 17-29, pi. 1 and pi. 2. figs. 1-7, pi. 3. figs. 1-4, pi. 10. fig. 3, pi. 4. figs. 1-6, 
and pi. 3. figs. 5-8. 
2. Fritillaria (Q. «& G.). Body elongate; endostyle arcuate; tail only f 
longer than the body ; a hood, consisting of a fold of the epidermis. F.fur- 
cata (Vogt), megachile, [hyiplostovia, formica, and urticans, spp. nn. : I, c. pp. 
29-37, pi. 6. figs. 1 & 2, pi. 6. figs. 1-6, pi. 6. figs. 3 & 4, pi. 10. figs. 1 & 2, 
pi. 6. fig. 0, and pi. 7. figs. 8 & 9. 
Kou)aJcwshaia[-skia'], g. n. No heart, endostyle, or intestine ; pharynx 
armed with 4 rows of solid teeth, covered with vibratory cilia. K. tcnvis, 
sp. n., id. 1. c. p. 37 et seq., pi. 10. figs. 4-0, and pi. 11. 
POLYZOA. 
Infundibulata. 
Profj R. Hartmann’s anatomical and microscopical researches into the 
organization of Halodactylus diaphanus tend to confirm in several points the 
views of Prof. Reichert on the organization of Bryozoa (see Zool. Rec. vii. 
p. 186). Arch. Anat. Phys. 1871, pp. 489-629, pis. 13 & 14. 
Cyphonautes. Prof. Allman, who observed this organism in considerable 
abundance in the Moray Firth, was not, however, able to pursue its develop- 
ment far enough to throw new light on its ultimate destination, but doubts 
if the view proposed by A. Schneider, that it is the larva of a polyzoon {Mem- 
branipord), will be found correct. Rep. Brit. Ass. and Q. J. Micr. Soc. (2) 
xii. pp. 395-397. 
H. Nitsche states, in opposition to E. Metschnikoff, that in Cyphonantes 
the intestine, like every other internal organ, is only provisional, perishing in 
the later development, and is not transformed directly into the intestine of 
the more mature animal. Z. wiss. Zool. xxii. pp. 471 & 472. 
Prof. Smitt replies to Nitsche on the development of Bryozoa. Q. J. Micr. 
Soc. (2) xii. pp. 246-248, and Z. wiss. Zool. xxii. pp. 281 & 282. 
Flustra ahyssicola, sp. n., M. Sars, Remark. Forms &c. pp. 19-22, pi. 2. 
figs. 25-30, Lofoden Islands, 120-300 fathoms. 
Flusframorpha [rectius Fbistri-'], g. n. Cells on both sides of the frond, as in 
Flustra, but much more calcareous, and covered with a calcareous coat, as in 
Eschara. The frond supported by cylindrical, and often inosculating, horny 
fibres, which margin the frond and traverse it in various directions. Flustra 
marginata (Krauss) and Eschara Jlahellaris (Busk). Gray, Ann. N. H. (4) x. 
pp. 167-169. 
Lepralia variolosa (Johnst.) and sp. indet., F. Schmidt, Mdm. P4tersb. xviii, 
p. 67, pi. 4. figs. 16 & 17, subfossil, at the mouth of the Jenisei. 
Idmonea punctata (Busk), id. ibid. p. 67, pi. 4. fig. 18, same locality. 
Cellepora pumieosa (li.), id. ibid. p. 68, pi. 4. fig. 19, same locality.
