﻿640 ME. L. V. DALTON ON THE [NoV. IQoSy 



striations on the lower half, the upper part above the posterior 

 angle being smooth. 



Remarks. — Fusus uniplicafus, Lamarck/ from the Paris Eocene^ 

 is very similar in shape and characters to this form. 



Locality. — Man choung, near Subagyidan (Minbu district). 



Family Yolutid^. 

 YoLTJTA PEEifODOSA, sp. nov. (PI. LYII, fig. 4.) 



Description. — Shell with a large anteriorly-acuminate body- 

 whorl and a fairly-prominent spire ; large transverse varicose ribs 

 and fine spiral striations. Aperture elongate, outer lip rather 

 thin, plaits of columella and canal not observed. 



Remarks. — This form appears to be a near relative of Valuta 

 nodosa, J. de C. Sowerby," from the English Eocene deposits, but 

 the transverse ribs are stronger than in that form, and the spiral 

 striae more marked than in V. Barrandii, Deshayes,^ from the: 

 ' sables moyens ' of Paris. 



Locality. — Man choung, near Subagyidan (Minbu district).. 



YoLUTA D'Aechiaci, sp. nov. (PI. LY, fig. 5.) 



1853. Vohtta indet., D'Arcliiac & Haime, ' Description des Animaux Fossiles du- 

 Groupe Nummulitique de I'lude ' p. 327 & pi. xxxii, jjg. 6. 



Description. — Shell small, spire conical and mucronate, body- 

 whorl large. The spire consists of five or more whorls with trans- 

 verse plications, giving rise to a line of granules along the suture 

 and 9,t the posterior angle of the whorls ; the last is clearly seen on 

 the body-whorl, of which the ornamentation is reticulate, owing to 

 the presence of spiral ribs of almost equal strength with the trans- 

 verse plications. Aperture narrow, columella plicate ; but neither 

 of these features is well seen. The width = 14 millimetres. 



Remarks. — This species appears to be identical with that of 

 which Yicomte d'Archiac found fragments in the yellow limestone- 

 of the Hala Range, India, and is clearly allied to Voluta amhigua 

 (Solander),'* an Upper Eocene species from Barton in Hampshire ;, 

 but the diff'erences seem to warrant a separate specific name. 



Locality. — K'orth-east of Subagyidan (Minbu district). 



Family Olivid^. 

 Oliva sp. 



Shell oliviform, of small size, smooth, with a large body-whorl and 

 a short prominent spire. Outer lip expanded beyond the penultimate 

 whorl. 



Locality. — Near Kyetubok (Minbu district).
