Dr. H. Woodward — On Fossil Shells, etc., from Sumatra. 493 



Dimensions: — Length about 3 A- inches; width of broadest part 

 nearly If inch. Number of whorls 6-8. 



This cone in its general form is evidently near to the Conns Noe 

 of Brocchi (Conchiologia Fossile Subapennina, 1814, torn. ii. p. 293, 

 tab. iii. fig. 3) ; but as it is only preserved to us in the form of a cast, 

 it is impossible to do more than point out approximately its specific 

 relations. 



Formation : — Obtained by M. Verbeek from the bed marked (5), 

 consisting of Tertiary Coral limestone, including internal casts of 

 Gasteropods and Conchifers, etc. (Verbeek, Geol. Mag. 1877, p. 444). 



Locality : — Government of the West Coast of Sumatra. 



29. Conns substriatellus (cast), H. Woodw. PI. XII. Fig. 2. 

 This cast — which approaches most nearly to Conns striatellus of 



H. M. Jenkins (Quart. Journ. Geol. Soc. 1863, vol. xx. p. 54, pi. vii. 

 figs. 3a, Sb) from Java, and particularly with the figures of a cone 

 referred to that species by Dr. K. Martin, in his work " Die Tertiar- 

 schichten auf Java" (Univalves), Leyden, 1879, p. 9, tab. i. figs. 

 2 and 2a — represents a conical ventricose shell ; the axis being short 

 in proportion to its breadth ; the whorls narrow, volutions 7-8 in 

 number, apex depressed, aperture narrow, slightly dilated at the base. 



Dimensions : — Height of shell 40 mm. ; breadth of shell at widest 

 part 28 mm. 



The figure given by Mr. Jenkins is evidently that of a young 

 individual, whereas our cast is that of an adult shell ; Dr. Martin's 

 figures represent three stages of growth, and his Fig. 2 most nearly 

 corresponds with M. Verbeek's specimen. 



It must, however, be borne in mind that the Javan fossils are 

 represented by specimens having the shell preserved, whereas the 

 Sumatran fossil is only a cast. I have therefore preferred to name it 

 C. substriatellus. 



Formation and Locality: — From the bed marked (5), found with 

 the preceding species. 



30. Cyprcea subelongata, H. Woodw. PI. XII. Fig. 3. 



This species is represented by four examples, two of which have 

 the shell partially preserved, which was tolerably thick ; in general 

 form it is somewhat amygdaloidal or ovato-elongate ; the spire is 

 slightly visible, but depressed ; the aperture is narrow at the upper 

 part, and somewhat dilated from the middle towards the base ; there 

 are well-marked indications of crenulations on the inner lip. 



Dimensions : — Length of figured specimen 33 millimetres ; 

 breadth of shell 21-J mm. The three other specimens referred to 

 this species are somewhat smaller. 



This shell closely resembles, in general form, the so-called Ovula 

 elongata of D'Archiac (Descrip. des Animaux Fossiles de l'lnde, 

 1854, p. 331, pi. xxxiii. fig. 9 and 9a) from the Hala Chain ; but 

 as the Sumatran fossil affords distinct evidence of crenulations on 

 the body- whorl, as above stated (although, unfortunately, our artist 

 has omitted to indicate them in Fig. 3), we have not ventured to 

 refer it to that species. Possibly — as the Indian shell is so like a 

 Cyprcea in general form — the artist of M. D'Archiac's plate may
