suture much, more deeply sunk in C. scalateUa, wliilst the longi- 

 tudinal ridges project upon the angle of the whorls so as to give 

 a coronate appearance. 



The three Cancellarice hitherto described from the Jamaican 

 Miocene are all akin to European fossils of the same date ; but two 

 of them belong to the type of the recent C. reticulata. The present 

 is of more decidedly Miocene aspect than either of the three pre- 

 viously described. 



Ovulum immunitum, n. sp., PI. XVI. Fig. 7. 



Fusiform-elongate, pointed at both extremities. Outer lip thick- 

 ened, extending in a nearly regular slight curve from the posterior 

 to the anterior canal ; slightly dilated anteriorly. Inner lip with 

 two strong folds at the anterior end. Aperture as long as the shell ; 

 narrow posteriorly, growing wider gradually until near the middle 

 of the whorl, then increasing in width by the expansion of the outer 

 lip and the recession of the whorl to form the slightly twisted pillar- 

 lip. Length about 20, breadth about seven mm. 



Allied to Ov- Leathesi, Wood, of the English Crag. It is nearly 

 of the same size, but is more slender in its proportions, and in some 

 particulars is more close to Ov. spelta, including under that term 

 both the fossil and recent species so called. 



Conus recogmtus, Guppy. 



C. solidus, Sowerby, Journ. Greol. Soc, vol. vi. p. 45. 

 C. recognitus, Guppy, Proc. Scient. Assoc. 1867, p. 171. 

 The name solidus having been used for another Cone, I proposed 

 in 1867 the name of recognitus for this species. 



Conus consohrinus, Sow., PL XVII. Fig. 4. 



Sowerhy, Journ. Geol. Soc, vol. vi. p. 45. 



I have referred this shell to Sowerby's species ; but if my determi- 

 nation be correct, Sowerby's description is in need of amendment. 

 The zones, or rather spiral ribs, can scarcely be called granose, 

 although they exhibit a tendency to become so towards the comple- 

 tion of the last Avhorl, which is usually devoid of the tiibercular 

 crowning of the previous whorls. 



This species was hitherto only known from Haiti, but it is now 

 added to the Jamaican list. 



Conus prototypus, PI. XVIII. Fig. 1, and PI. XVII. Fig. 9. 



Somewhat pyriform, finely striate anteriorly, becoming quite 

 smooth on the angle of the whorls, which bear a rather indistinct 

 keel ; spire mucronate, rather elevated ; aperture somewhat widened 

 towards the anterior canal. 



Miocene, Trinidad. A cone which departs very considerably from 

 the usual type in its swelling outlines and the consequent direction 

 and shape of the aperture. It is more of the shape of C. hulhus than 

 of any other species I know. It is, however, probably a young 

 specimen.
