84 THE NAUTILUS. 



Szeehenyi obtained a single specimen. These shells were detected 

 by French missionaries, and the locality, although furnishing several 

 species of mollusca, is not a rich one as far as shells are concerned. 

 IManorbis persicus Anc. 



Testa compressa, non carinata, olivaceo vel subgriseo-cornea, oblique 

 confertim striata, nitidula, pro genere relative solidiuscula, utrinque 

 lateumbilicata et concava, discoidea. Spira apice minute immerso. 

 Anfractus 5, convexi, sutura impressa, sat lente crescentes ; ultimus 

 supra convexo-declivis, post medium rotundato-subangulatus, infra 

 depressus. Aperture obliqua, transverse oblonga, sublunata, intus 

 obscure albo-labiata (in peradultis), marginibus callo appresso junctis. 

 Diain. mag. 9. min. 7 -J, alt. 2| mill. 



Hab. — Tehe>an, prov. Trak-ajemi, Persia ; Salmas, north of Lake 

 Urmiah, Persia (Comm. G. Nfegele). 



This is allied to, but different from, PL subangulatus Phil., from 

 which it is easily distinguished in being much less distinctly angled 

 below the periphery. The above description is drawn from the largest 

 specimen sent me by Herr G. Nsegele ; some also probably mature 

 are much smaller and more rounded. 

 Phjsa Moussoni Ancey. 



Pliysa lirata, Mousson in Journ Conch., 1874, p. 43, non Tristram 

 (1863), nee Craven (1880). 



The name Physa lirata having been used several times, I should 

 call attention to the fact that Dr. Rudolf Sturany (Catalog der Suda- 

 frik. Land- und Siisswasser-Moll., 1898, p. 76), not being aware that 

 several years ago I proposed to substitute Physa Oraveni for lirata 

 Craven (not of Tristram), calls the latter Oraveni Sturany, while I 

 should claim for the priority of Craveni, Ancey ; but this .induces me 

 also to change lirata Mousson to Moussoni Ancey, as the specific 

 name lirata must be retained for the species originally described from 

 Madagascar. 



Ph. Moussoni Ancey was discovered in Mesopotamia by Dr. 

 Schaefli. 



Helicina Sundana Ancey, nom. nov. 



The above name I suggest for Helicina exserta Martens, a species 

 occurring in the islands of Saleyer, Kalao and J am pea, between Cel- 

 ebes and Flores, as another Helicina from Cuba has long ago been 

 described under the same name of exerta, " Gundlach, MSS.," by 

 L. Pfeiffer (see Malak Blatter, v, 1858, p. 194).
