A. micronculpta. This specimen somewhat answers to Mr. Blanford's 

 description of Mealia dccussata. 



Assiminea brevicula, Pfeiffer, PI. VII, Figs. G—6 A. 



P. Zool. S. 1854, as Hydrocena brevicula, from Singapore; var. = A. miniata, 

 Martens, Ann. Mag. XVII, 1866, p. 206, Singapore, long. 9, diam. 4$ mil. ; var. = A. 

 rubella, Blf., Ann. Mag. 1867, Irawady Delta, long. 5, diam. 4 mil.; var. = Hydrocena 

 marginata, Morelet, J. de C. 1855, Bangkok, long. 6 — 8, diam. 4 — 5 \ mil. ; var. ? = A. 

 rubida, Gould, P. Bost. S. 1859, Loo Cnoo Islands. 



A very abundant, variable and widely distributed species ; there are 

 specimens in the Museum from Singapore, Malacca, Andamans, Borneo, 

 Irawady Delta, Arakan, Philippines, and Amoy. 



The Port Canning specimens are mostly of the typical colouration 

 " comeo-fulva" and measure — long. 7, diam. 5 rail.; there are also subvarieties, 

 bicolor and bibalteata. Mons. Morelet's remarks on this species, Ser Conch. 

 IV, p. 294, are excellent " cette coquille peut varier de 6 a 9% mil., de 

 couleur fauve ou rougedtre ;" I will add that it varies also with regard to 

 the infrasutural impressed lines, of which there are sometimes two, as in 

 typical A. rubella and miniata, sometimes only one, as in A. brevicula and 

 marginata ; at Port Canning both exist together, with every possible 

 intervening form. I am indebted to Mr. Wood- Mason for the figures now 

 given of this small mollusk. Von Martens describes his A. miniata as 

 having the head and foot of a pale red colour. 



Paludomcs blanfordiana, Gr. Nevill, PI. V, Figs. 3 — 3 A. 



J. A. S. B. 1877, p. 37, Ava, long. 19, diam. 15 and var. from Gowhatty, long. 

 20, diam. 15 mil.; Con. Indica, pi. 108, fig. 9, "Tongoop," as " P. labiosa" (not of 

 Benson) . 



I think the figures now given will prevent this species ever again being 

 confused with its undoubtedly distinct Tenasserim ally, the true P. labiosa 

 of Benson. I named the species after Mr. H. F. Blanford, to whom 

 I am much indebted for permission to make free use of his collection, 

 which he has temporarily deposited under my charge in the Museum, a 

 privilege I much value owing to the great care and accuracy with which 

 the exact localities of the species have been recorded. 



Paludomus peteosa, Gould, PI. V, Fig. 5. 



P. Boston Soc. 1843, Tavoy, as Paludina petrosa ; = Paludomus labiosa, Benson. 

 Ann. Mag. 1856, Tenasserim Valley, long. 13, diam. 11 mil. (not of the Con. Indica, or 

 Conch.-Cab.). 



After a careful study of Gould's original description, I have no hesita- 

 tion in uniting his species to Benson's, especially as both are from the 

 Province of Tenasserim j Benson probably overlooked it, owing to its having
