trorsc variety at Pliic Tliau in the l\'.iiasscrini Valley. A fragment 

 of H. Safnniiii, Goultl, was also sent from that valley, where 

 H. retrorsa and anceps, Gould, were found abundantly, and //. 

 Theodori, Piiil., very sparingly. A shell, apj)arently referable as 

 a variety to the Darjiling //. Castra, nobis, was once met with 

 at Pyii, l)etween Mauhnain and Tavoy. Helix Merguiensis, Ph., 

 H.gabata, Gould, a small var. of //. delibrala, nobis {procumbensi, 

 Gould), and //. Iionesta, Goidd, occurred both at INIauhnain and 

 in the valley of the Tenasserim River, where H. resplendens, Ph., 

 was not rare. The widely spread H. similnris, Fer., is noted from 

 Thyet Myo and Prome, on the river Irawadi, and a sharply- 

 keeled variety of H. rotatoria, V. d. Buseh, hitherto supposed to 

 be peculiar to Java, inhabits the banks of the same river, lower 

 down, at Akaouktoung. None of the Helices, described by Gould 

 or others from the former dominions of the Burmese Empire, 

 apjjcar to have escaped the researches of jMr. Theobald, who has 

 added largely to the list, several other species of Helix remain- 

 ing to be described. 



Rhaphaulus [Anaulus and Megalomastoma) Chrysalis, Pfr., 

 from Maulmain, in a more perfect condition than the type spe- 

 cimen, shows a much longer tube running up the penultimate 

 whorl than either bomhycinus or Lorraini, Pfr., and its colour is 

 a rich chestnut. A dead specimen of Megalomastoma sectilabre, 

 Gould, from Yanglaw on the Tenasserim River, confirms an opi- 

 nion communicated last year to PfeifFer, and derived from Gould's 

 and Mason's observations, and from a view of Pfeiffer's supposed 

 specimen of sectilabre from Borneo, that, although allied to, it 

 was quite distinct from my Bornean M. Anostoma, with which 

 PfeifFer had believed it to be identical. The channel in M. Ano- 

 stoma (Annals, 1852, vol. x. p. 269-270) is on the inner lip, as 

 in M. ahum, Sow. In sectilabre it appears on the right lip, near 

 the top of the aperture. The latter is a more solid shell, with 

 the spire more slender and longer in proportion ; the suture is 

 distinctly marginate ; the ])eristome is white (not coloured, as in 

 M. Anostoma), and presents a contrast with the orange- chestnut 

 interior of the aperture ; the apex also is not pale or white, as in 

 the Bornean species.
