﻿636 MR L. V. DALTON ON THE [NoV. I908, 



Remarks. — Only one left valve was collected, but from the 

 figure of A. Clot-Beyi (Bellardi),^ that form, found in theMokattam 

 Beds of Egypt (Middle Eocene), appears to be related. 



Localitv. — I^orth-east of Subagyidan (Minbu district). 



Family Anitixid^. 

 Theacia sp. 



An oval inequilateral cast, with one marked posterior plication, 

 and some indications of a second, curving anteriorly from the umbo, 

 appears to be referable to this genus. 



Locality. — Near Kyetubok (Minbu district). 



Family Caedhd^.

1840. Cardium amhiguum, J. de C. Sowerby, Trans. Geol. Soc. ser. 2, vol. v, pt. ii, 

 p. 328 & pi. xxiv, fig. 2. 



Description. — Shell of moderate size, oval, inflated, inequi- 

 lateral. Beaks pointed, prosogyrous. Hinge-margin angular, 

 making an obtuse angle with the posterior margin, which passes 

 under a rounded right angle into the crenulate ventral margin, and 

 this again into the anterior margin under a rounded obtuse angle : 

 the angle between the anterior and cardinal margin being also 

 obtuse. The ornamentation consists of fairly-strong radial ribs, 

 which are rounded and separated by interstices of about equal 

 width. 



Localities. — Minbu district: near Kj'etubok ; and north-east 

 of Subagyidan.

Description. — Shell obovate, inflated, almost orbicular, with 

 numerous concentric laminae, some thin, but thicker ones forming 

 fairly-regular concentric ribs, crossed by numerous radial striations, 

 raising small granules towards the margin. 



Remarks. — This species, as will be seen from the synonymy, is 

 known both from the Eocene of North- Western India and from the 

 Miocene of Burma. 



Locality. — 2 miles west-south-west of Myegya (Thayetmyo 

 district).
