5G1 
A short abstract of Metschnikoff ’s paper on Medusft Siphono- 
phora [Zool. Rec. xi. pp. 625 & 526] is given in Q. J. Micr. Sci. xv. ppi 
79 & 80; of Van Beneden’s on Hydractinia [Zool. Rec. xi. p. 525], tom. 
cit. pp. 80-82. 
Local Lists, Gknera, and Species. 
A list of the Calycozoa, Ctenophora., Discophora^ and Hydrozoa, known 
from Greenland, is contributed to the “Arctic Manual” (pp. 186-190) 
by the Recorder. 
Clark, Am. J. Sci. (3) x. p. 42, describes 5 new species of Hydrozoa 
from New England : Gonothyroea tenuis^ Obelia hidentata (pi. iv. fig. 10), 
hicuspidata (fig. 11), Operoularella pumila (figs. 7-9), and Halecium arti- 
culosnm. The following are figured: — Clytia johnstoni (fig. \),noliformis 
(McCr.) (fig. 2), Calycella syringa, Hincks (figs. 3-5), and Campanularia 
calceolifera^ Hincks (fig. 6). 
F. E. Schulze (7) enumerates the Hydroidce^ Medusce, DiphyidcBy and 
Ctenophora, observed during the cruise of the “ Pommerania,” with re- 
marks on the specimens examined, and notes on localities, depths, &c. 
One new species is described : Aglaophenia {Lytocarpia) mcehii^ p. 135, 
pi. ii. figs. 3-5 (Korsfjord). Figures of 2 species of Tima are also given 
(figs. 6 & 7). 
A. M. Norman enumerates 10 species attached to the Falmouth- 
Lisbon cable (“ Submarine-cable Fauna,” by J. Gwyn-Jeffreys, and the 
Rev. A. M. N.), Ann. N. H. (4) xv. pp. 172-174. Two new genera 
are established, viz. : — 
Acryptolaria, Norman. “Zoophyte ramose, irregularly branched, 
branches composed of several tubes; hydrothecse rather distant, sub- 
spirally or alternately arranged, tubular, not contracted at the base and 
prolonged into the branch itself; mouth somewhat patulous.” A. ex- 
serta (Busk), p. 172, pi. xii. figs. 1 & 2 (allied to Grammaria ahietina, 
Sars, which^s not Salacia,IjB,m.). 
Scapus, Norman. “Zoophyte in the form of a spongious mass rolled 
in cylindrical form round the stems of branching Hydrozoa, and con- 
sisting of a series of somewhat closely packed subquadrate hydrothecae, 
closed in above, except at the centre, where the hydrotheca projects in 
the form of a short simple cylindrical horny tube. S. tiihulifer, sp. n., 
p. 173, pi. xii. figs. 1 & 3 (on Acryptolaria exserta ; comparable with 
Coppinid). 
Wyvillb-Thomson describes a gigantic (7 feet 4 inches high) Mono- 
caulus dredged in the North Pacific, 34° 37" lat. N., 140° 32" E., depth 
1875 fath., and 37° 41" lat. N., 177° 4' W., depth 29a0 fath. ; Nature, xii. 
pp. 665 & 656. 
The occurrence of Lucernasia {Calvadosui) campanulata, Jjmx., in the 
Adriatic near Trieste, is noticed by Graffb (4, a). L. auricula, Fabr. [= 
octo-radiata, Lmk., nec L. auricula, Fabr.] is figured in McIntosh’s 
Mar. Invertebr. of St. Andr. pi. iii. figs. 11 & 12. Graffe (4, b) 
enumerates for each month the species of BeroidcCf Acalephm, and 
1875 , [vOL. XIT.] oo
