Malak. Blat. xii. p. 16.— This species has been observed alive by Berendt, 
ibid. p. 208 ; he states that this species, as well as II. caduca (Pfr.), has the 
hinder end of the foot truncated and provided with a cavity.

[Hyalina] Helix marsii. This name is to be substituted for H hinneyana 
(Morse), the latter being preoccupied : Try on. Am. Journ. Conch, i. p. 188. 
[This change of name will be necessary only when Hyalina or even Zonites 
are not recognized as genera distinct from Helix.] 
[Hyalina ] Comdus chersina (Sa}^). Some differences in the form of the 
shell between this American species and the European H. fidva (Drap.) are 
pointed out and figured by Morse, Journ. Portl. Soc. Nat. Hist. i. 
[Macrocyclis] Helix voyana^ Newcomb, Am. Journ. Conch, i. p. 235, pi. 25.

Pseudohyalina, Morse, 1 . c. The lateral aculeate uncini of the radula, agree- 
ing in form with those of Hyalinaf comprise about one-third (in Hyalina 
only one-sixth or one-seventh) of the whole number of plates in a row ; 
moreover the buccal plate is more like that of Valloniaj and the shell is 
striated or ribbed, not polished. This new genus comprises Helix exigua 
(Stimps.) and II. mimcscida (Binnoy). 
Helicacea (Odontognatha). 
Pattda complementaria and P. hystricelloides, sp. n., Mousson, Journ. Conch,

noidea, Anthony, Am. Journ. Conch, i. p. 351, pi. 25. fig. 3, North Caro-

Planogyra asteriscus, Morse, Journ. Portl. Soc. Nat. Hist. i. p. 27, pis. 2 & 8. 
The differences in the sculpture of the shell and buccal plate, considered to 
be of generic importance by Morse, seem scarcely to justify a separation 
from Patida. Lives on wet boggy ground. 
StriaUira, g. n., Morse, 1. c. Central plate of the radula enormous ; buccal 
lamina almost smooth, with a median furrow and notch. S. ferrea^ sp. n., 
and S. miliumj sp. n., 1 . c. pp. 17-19, pi. 7. 
HelicodiseuSf g. n., Morse, 1 . c. Buccal plate with very strongly diverging 
striae and smooth edge. Type Helix lineata (Say), p. 25, pis. 2 »& 8. 
Strobila, g. n., Morse, 1. c. Buccal plate smooth, Avith the edge minutely 
crenate. Type Helix labyrinthica (Say), p. 26, pi. 8. 
Helix conspectaj Bland, Ann. Lyc. Nat. Hist. New York, viii. p. 163, San 
Francisco, California. Allied to II asteriscus (Morse) and II mazatlanica 
(Pfr.) j all three figured in woodcuts, pp. 163 & 164. 
Angiiispira, g. n., Morse, 1. c. Type Helix alternata. Buccal plate strongly 
striate, longitudinally and transversely, with the lateral ends truncate, whereas 
in the true Patida^ for example P, striatella (iVnthony), it is only longitudi-
