16. The genus Pomatiopsis (Try on), restricted by Mr. Stimpson, forms a sub- 
family, Pomatiopsince, being terrestrial, although it is provided with a true 
gill and has no trace of a vascular lung j it lives in company with Succinea 
and Helix electrinu near the borders of streams and marshes j the mode of 
progression of the animal is ‘^stepping,” which it affects by affixing the 
disk -like extremity of the snout to the ground as far ahead as possible, 
^ in a manner somewhat similar to that of Truncatella [and Pedipes], This 
observation was made by the author on P. lapidaria. Amnicola say ana 
(Adams) belongs probably also to this genus. Cecina and Blanfordia (A, 
Adams) have considerable resemblance to it in form and habits j but neither 
' their lingual dentition nor their respiratory organs are known. 
[Dr. Stimpson does not appear to have been acquainted with 
a paper, Ueber einige Brackwasser-bewohner aus den Umge- 
bungen Venedigs (Wiegm. Arch. 1858, xxiv.), in which most 
of the genera mentioned are treated of, and which especially 
contains information on Hartmann’s Hydrobia (acuta, Drap., 
and vitrea, Drap.), on the position of Pyrgula among the Hy~ 
drohice (instead of Melanice), and on the H, thermalis of most 
authors, which is not the true thermalis of Linne, but H. apo~ 
nensis (Martens) .] 
G. W. Tryon reviews this memoir of Dr. Simpson in Am. 
Journ. Conch, ii. pp. 152-158, and defends his opinion that the 
Rissoidce, Skeneidce, and Amnicolidce should be separated as 
distinct families. 
Hydrobia haltica (Nilss.). Radula described, but not figured by Eberhard, 
/. c. p. 11. 
Hydrobia ligurica, etrusca, macei, charpyi, lusitanica^ sp. n., from Italy, 
Southern France, and Portugal. Paladilhe, Rev. et Mag. Zool. pp. 89-95. 
Cingula epidaurica and Hydrobia strongylostoma, sp. n., Brusina, Faun. 
Moll. Dalmat. p. 29, pi. 3. figs. 10 and 11, Adriatic. 
Bugesia, n, g., Paladilhe, 1. c. p. 54, pi. 13. figs. 8-10, a little Hydrobia-like 
shell, but tuberculated like a Cerithium. The species is called B. bourguignati, 
and has been found in the alluvium of the Lez, near Montpellier. 
Paladilhia. A list of the known species, including Paludina bicarinata ' 
(Desmoulins), has been given and a new species, P. bourguignati, added by 
Paladilhe, 1. c. p. 94. The latter is figured pi. 13. fig. 4-7 j it occurs near 
Montpellier. The animal has been found alive, but could not be satis- 
factorily observed on account of its extreme shyness ; it liked to stay near 
the surface of the water, a small part of the aperture emerging from the 
Walter. 
Amnicola eincinnatiensis (Anthony) has been found also in Mexico. Tryon, 
Am. Journ. Conch, ii. p. 11.
