lAmruBa auricularia,\ 2 ix. persicUf Bourguignat in litt., Issel, 1. c. p. 47, Ker- 
man. 
Lhnnceus subulatus (Bunker) = Omphiscola pugzo (Beck), yery near to L. 
attenuatus (Say), Mexico. Martens, Mai. Blatt. xii. p. 68. 
Physa. Tiyon enumerates sixty species of this genus from the United 
States, and carefully compiles their synonymy. Am. Conch, i. pp. 165- 
173. He says (p. 223), ^^The specific characters in the Physce, though not 
^ very marked, are really very constant ; and, therefore, probably not only most 
of those species recently described by Lea and those herein desciibed Avill 
stand, but we may reasonably conclude that many yet uncharacterized 
species inhabit our waters.” 
Physa niayarmsis, altanensis, crocata^ fcyrsheyi, tenuissima, halei, fehiyerii, 
nicklimij grosvenoriiy whitei, saffordii, hawnit, anatina, parvaj shoxvalteriij 
smithsomana, tvarreniana, traskii, striata, hlandii, nuttalii, venusta, hordacea, 
and hrevispira are new species described by Lea, Proc. Ac. Nat. Sc. Philad. 
1864, pp. 114-116, from the United States or Canada. 
Physa propinqua, cooperi, sparsestriata, diaphana, maUeata, distinguendaj 
politissima, occidentalis, primeana, lata are new species described by Tryon, 
Ajn. Journ. Conch, i. pp. 223-227, pi. 23. figs. 6-14, United States, most 
pf them from California j P. primeana, from Long Island. 
Physa fragilis (Mighels) = ancillaria (Say) viir. The shell was found in 
a millstream charged with wood-dust from a neighbouring saw-mill. In 
the waters above the mill P. ancillaria occurred in abundance, with no trace of 
P, fragilis. This mill was afterwards destroyed, and nearly synchronous 
with this event was the entire obliteration of P. fragilis and the recurrence 
of the normal form P. ancillaria ; nothing approaching this abnormal form 
has elsewhere been observed in the State of Maine. Morse, 1. c. p. 44. 
Physa mexicana (Phil.) with some smaller varieties and P. osculans (Halde- 
man) inhabit Mexico. Martens, Mai. Blatt. xii. p. 67. 
[Aplexa'] Bulinus herlanderiamis, sp. n., Binney, Am. Journ. Conch, i. p‘. 51, 
pi. 7, fig. 8, Texas; Physa nitens (Philippi) aurantia (Carpenter), 
Mexico. Martens, Mai. Bliitt. xii. p. 67. 
Planorbis newb&t'ryi (Lea), from California, again described by Lea. The 
tentacula do not seem to be so long as is usual in Planorbis ; therefore Lea 
proposes a new genus, Meyasystropha, Proc. Ac. N. Sc. Philad. 1864, p. 5. 
For the same shell Binney proposed the generic name Carinifex in 1863 ; 
he describes and figures it in Am. Journ. Conch, i. p. 50, pi. 7. figs. 6 & 7. 
Planoi'bis hornii, sp. n., Tryon, Am. Journ. Oonch. i. p. 231, pi. 22. fig. 16, 
Fort Simpson, British America ; P.\.oregonensis, sp. n., Tryon, 1. c. fig. 17, 
Pueblo Valley, Oregon, from a thermal spring, water above blood-heat. 
Planorbis ticmidus (Vii'.'), tenuis (Phil.) (Caipenter) ?, and halde- 
mani (Bunker) ai’e Mexican species redescribed by Martens, Mai. Bliitt. xii. 
pp. 64-56. 
Ancylus reticidatus, sp. n., Gassies, Journ. Conch, xiii. p. 212, New Cale- 
donia ; A. altus and subrotundatus, sp. n., Tryon, Am. Journ. Conch, i. p. 230, 
pi. 22. figs. 16 t& 16, California. 
Ancylus jani, var. major, Issel, Mem. Accad. Torin. xxiii. p. 44, pi. 3. 
figs. 68-61, from Erivan.'
