Dr. Gould continued his account of the Shells from Bur- 

 mah, received from the Rev. Mr. Mason. 



Paludina doliaris. Testa tenui, conico-globosa, luteo-virides- 

 cente, arctissime umbilicata ; anfract. 5 ventricosis, striis minu- 

 tissimis reticulatis, costulis numerosis inequalibus, purpureis, cinctis; 

 apertura sub-circulari ; columella reflexa, non appressa, alba ; labiis 

 postice disjunctis. Long. 11-10; lat. 9-10 poll. 



Differs from P. Burroughiana and elongata in form and aper- 

 ture ; but is nearly allied to P. subcostata, Griffith's Cuvier. 



Paludina petrosa. Testa solida, imperforate, subglobosa, apice 

 erosa, saturate viridi, rufo fasciata ; anfract. 3, ultimo amplo, sutura 

 praecipue marginata. ; apertura semi-circulari, columella late planu- 

 lata. rufescente ; intus nigrescente vei holoserica ; operculo apice 

 subcentrali, dementis concentricis. 



Resembles Anculotus or Littorina, but its place is determined 

 by the operculum. 



Melania eatana. Testa turrita, solida, fusco-virescente, apice 

 erosa, anfract. 6 — 7, planulatis, postice sub-coronatis, costulis longi- 

 tudinalibus et volventibus gemmularum series tres efformantibus ; 

 apertura angusto-ovata, postice coronata, intus coerulescente, co- 

 lumella alba. Long. 1 ; lat. 2-5 poll. 



Very closely resembles M. Hydeii, Conrad. 



Modiola varicosa. Testa fragili, lucida, inequilaterali, trans- 

 verse ovato-oblongata, sub-falcata ; colore luteo-viridescente, supra 

 costa umbonali maculis venosis obliquis notata ; margarita argentea, 

 ad umbones purpurea. Long. 1-2 ; lat. 7-20 ; alt. .5. 



A beautiful and delicate shell, which I suspect to be an inhabit- 

 ant of brackish, or even fresh water.
