YOLIJTA (?) BIEMANICA, Sp. nOV. (PI. LYII, fig. 10.) 



Description. — Shell coniform, height not less than 32 milli- 

 metres ; depressed conical spire, of which the apex may have been 

 mucronate as in Imhricaria; aperture narrow. Columella straight, 

 with spiral plications, of which the anterior are the stronger ; outer 

 lip thickened. 



E em arks. — ^The smooth character of the shell renders it in 

 appearance very like a Conns, but it is readily distinguished by the 

 columellar plaits. Its true generic position must be regarded as 

 doubtful. In this connexion the suggested relationship ^ of Gosavia 

 to Conns and to Imhricaria is interesting, as this species also 

 possesses characteristics belonging to both genera. 



Locality. — Yenanine choung, near Banbyin (Thayetmyo 

 district). 



Family Teeebeid.^;. 

 Teeebea sp. 



(?) 1901. Terehrum sp., Noetling, Pal. Ind. ii. s. vol. i, no. 3, p. 340 & pi. xxii, 

 fig. 19. 



Description. — Shell small, turretted; apical angle small. 

 Whorls ornamented with transverse ribs, curved on the lower part ; 

 but in a narrow band below the suture, separated from the main 

 portion of the whorl by a faintly- marked furrow, the ribs are 

 straight. 



E em ark. — This species appears to be identical with Dr. IS'oetling's 

 Terehrum sp., from the zone of Paracyatlius cceruleus at Yenangyat. 



Locality. — South-west of Mindegyi (Thayetmyo district). 



Family Coxid^. 

 Coxus scALAEis, Martin. 

 1879-80. Conus scalaris, Martin, ' Tertiarschichten anf Java 'p. 12 & pi. ii, fig. 4. 



Description. — The shell (a cast) consists of eight whorls with 

 deeply-canaliculate sutures, and a large acuminate body-whorl. 

 The earlier six whorls form a steeply-inclined cone, but the last 

 two descend more gently. Ornamentation not observed. 



Eemark. — The peculiar step-like form of the spire of this 

 species readily distinguishes it. 



Locality. — A mile and a half east-north-east of Ngalaingyoung 

 (Thayetmyo district). 



Conus avaensis, Xcetling.

Localities. — Letpan choung, 10 miles east of Sawmyo (Pakokku
