Eleutheria. Prof, de Filippi Q. c.) notices the diflerences tliat exist in the 
mode of reproduction in the species of this genus. In the species which he 
found in the marine aquaria of the Zoological Society of Turin he found no 
males. The ova were developed in a sac everywhere bounded by the endo- 
dermic layer. Tlie development of the ova was not traced beyond the pla- 
uula ” stage. Prof, de Filippi thinks that the differences in the structure of 
the umbrella, in the mode of locomotion, and in the position of the sexual 
organs between the species of this genus and Clatlonema are sufiicient to 
elevate Eleutheria to the rank of a family. 
Local List. — Marcusen gives the following list of species found by him in 
the Black Sea : — Medusa aurita, Sarsia pidchella and S. tubulosa, Campanu- 
laria voluhilis and C. geniculata, Actinia zonata, Rjithke, and Pletirohranchia 
rhododactyla. Archiv f. Naturg. xxxiii. Jahrg. 1. Bd. p. 358. 
Histology. — The resume of Prof. Reichert’s paper on the contractile sub- 
stance and intimate structure of the Campanularice, Sertularice, and Ilydridce 
is translated in Ann. &; Mag. Nat. Hist. vol. xix. 1867, pp. 54-58 {vide Re- 
cord for 1866, p. 632). 
Development. — Dr. Strethill Wright (/. c.) p. 333 gives some hints as to the 
best mode of observing the reproduction of Zoophytes. He incidentally re- 
marks tliat the development of the planula into the hydroid, with the suc- 
cessive development of the polypary, varies very much with the genera and 
species from which the planulae are derived : thus in Sertidaria pumila and 
Campanularia dichotoma the first young polyp is complete in its polypary in 
a few hours after the planula is discharged, while in JEquorea and Ilydrac^ 
tinia the same process requires weeks. The Ephyrce of the Stcganophthal- 
mata remain in the polyp-phase, if well fed and kept in a darkened place, for 
years j but if exposed to sunlight and not fed they may be forced to assume 
their medusoid state. 
Hackee’s researches on the Qeryonidce (Ann. k Mag. Nat. Hist. vol. xix. 
1867, pp. 63-67) have been already alluded to in the ^Record’ for 1865, 
p. 780). 
Taxidermy. — Prof. Pagenstecher gives a note ‘^Ueber Aufstellung der 
Quallen in den Museen,” in Zeitsch. f. wissensch. Zoologie, Bd. xvii. pp. 379- 
380, 21st Mar. 1867. He places the Medusae in a mixture of two parts of 
common salt and one part of alum, and leaves them in it for from 24 to 48 
hours ; then putting them up in weak spirits (the addition of a little corro- 
sive sublimate, as in Goadby’s solution, is without any advantage and is ra- 
ther hurtful) he suspends the specimens for the museum by means of glass 
rings, into which they fit, or upon which they rest. Rings for this pur-
