VALVATIDiE. 
Valvata naticina, Menke (Zeitschrift fiir Malakozoologie, 1846), has been 
i^cognized by Dr. Hensche in a shell found near the mouth of the river 
Memel or Niemen, Province of Prussia. As this species is very little known, we 
may add Dr. Hensche’s description of it : — Testa orbiculato-convexa, anguste 
umbilicata, solidula, nitida, hand diaphana, tenuissime striata ; supra corneo- 
flava, infra albido-csesia ; spira convexo-depressa ; anfr. 3^, celeriter crescentes, 
suturaobsoleta distincti, ultimus convexus ampliatus; apertura subverticalis, 
ampla, subcircularis ; peristoma simplex, continuum, in maryine columellari 
nec non in margine dextro leviter excisum, margins columellari supra reflexi- 
usculo, umbilicum ad ^ latitudinis tegente, supra ad { longitudinis affixo, 
cum margine extemo angulum rectum formante. Diam. maj. 6-2, min. 6-3, 
alt. 6’6, ap. long. 4, lat. 3 mm. Operculum comeum, supra subangulatum, e 
centre spira lata lineatum. The lingual dentition differs from that of 
its congeners in ftie external plates being very narrow, without any denticu- 
lation. This species is perhaps identical with V. menkeana ( Jelski, Journ. 
Conch. 1863). Schrift. phys.-okon. Ges. Kenigsberg, 1866, pp. 101-106. 
Valvata glohuUna (Per.) is another European species almost unknown, and 
enumerated in his list of species from Southern France by Paladilhe, Rev. et 
Mag. Zool. 1866, pp. 168-171. The French species of Valvata are referred by 
him to three groups, viz. 1. Piscinales) 2. Glohuleuses) 3. Planorhiques {V, 
a'istatcif Miill.).

- Ampullaria. A. urcem^ var. purpurascens, A. effusay var. conica and var. 
tristis, and Marisa cornu arietis, var. stvifti, occur in Trinidad, together with 
the typical forms of the same species. Marisa \_Ampullarid\ knorriy Phil., 
ought not to be distinguished from cornu arietis, which is very common in 
most of the streams, and even in the fountains of the botanic garden of that 
island. Amp. urceus is eaten in great numbers by the Africans and savage 
squatters. Amp. ejfusa has been observed gliding along the surface of the 
water like Pkysa. Guppy, Proceed. Scientif. Assoc. Trinidad, i. pp. 28, 33, 34.
