pp. 5, G, pi. 3. figs. 3, 6, 6, Sandwich Islands, The author gives in the same 
paper a list of the species of LimncBa inhabiting the Sandwich Islands, con- 
taining the following described species: — L. oahuensis, Souleyet,=a^MW, Sou- 
ley et,=ro/?<^flr^(7, Gould; also reticulata {Q ow\di) ^ nmhilicata (Mighels), and 
producta (Mighels) ; finally turgidula, compacta, and amhigua, spp. nn. He 
states that sinistral and dextral specimens are found in company with each 
other, the latter being rare in all localities. This confirms an opinion pub- 
lished by the Recorder in Ann. N. II. L. c. pp. 4-6 ; the new species figured, 
pi. 3. 
Tompliolyx, Lea. The external and anatomical characters of this genus 
are fully described from specimens found in Clear Lake, and belonging pro- 
bably to P. leana, II. & A. Adams, var. solida. The principal of them are ; 
— buccal plate subcordiform ; lateral jaws absent ; genitalia on the left side 
(in Limneca on the right) ; tentacles stout, cylindrical, slightly globose at the 
tips ; eyes sessile on the front of the head near the inner bases of the tenta- 
cles ; in some individuals an aggregation of pigment-cells near the tips of the 
tentacles, which lias been taken for a second pair of eyes, but it is nearly or 
entirely absent in others. Dali, Ann. Lyc. N. II. ix. pp. 333-340, pi. 2.

species, by V. d. Broeck, Ann. mal. Belg. iv. (1869) p. 90, pi. 2. fig. 5, St.

Allied to Fh. sinuata (Gould). 
CostatcUa, new subgenus for Physa costata, Newcomb, on account of the 
ribbed shell. Dali, 1. c. p. 355. 
Planorhis. Ficiims has made anatomical researches which 
show a considerable difference in the male organ of several of 
our common European species of this genus. In PL vortex, leu- 
costonius, sph'orbis, alhus, and contortus it is furnished with a 
very elegant calcareous sting, which is not thrown away as the 
sagitta of Helix. Planorbis corneus, nitidus, and complanatus, 
Drap. [fontanus (Lightf.) 1, want this organ. The first of them 
is further distinguished by a well- developed albuminous gland, 
the two latter by csecal appendices on the corpus cavernosum. 
The author proposes, hut with some hesitation, a new generic 
name, Appendiculata, for these two last-named species. Z. ges.

Planorhis corneus (L.). Inflated variety called formerly by Charpentier 
etruscus, Ziegl., then meridionalis, and PI. similis, Bielz, which is the true 
etruscus of Ziegler, living together at Casaleone. Betta, Moll. prov. Veron,
