R. J. L. GUPPY ON THE MIOCENE FOSSILS OF HAITI. 521 



spire is usually more concealed, while the wing is not so much ex- 

 tended ; the young shells of this species are also much less elongate 

 in their proportions. There may be other differences ; but the spe- 

 cimens in the Geological Society's collection do not enable me to 

 speak with certainty of them, as no example is perfect. One (in 

 fragments) attained the dimensions of at least six inches long and 

 four wide. 



29. Strombes haitensis, Sow. G. J. vol. vi. p. 48, pi. ix. fig. 7. 

 Gabb regards this as being S.bituberculatus, Sow. 



30. Strombes proximes, Sow. G. J. vol. vi. p. 48, pi. ix. fig. 8. 



Strombits pugilis, C. Moore. 



pugiloides, Guppy. 



ambiguus, Sow. 



In his synonymy of S. pugilis, Gabb includes the following : — am- 

 biguus, Sow.; bifrons, Sow.; and pugilis (=pugiloides, Guppy). 



Whilst admitting much truth in Gabb's rectification, I cannot go 

 so far as to regard S. bifrons as a synonym of either S. pugilis or 

 S. proximus. 



In Geol. Mag. 1874, p. 433, I have given what I consider good 

 reasons for separating the fossils formerly regarded by Mr. Carrick 

 Moore and myself as S. pugilis under a distinct name, and I pro- 

 posed that of pugiloides. I am, however, after an examination of 

 the types in the Geological Society's collection, prepared to agree 

 that S. proximus and S. ambiguus are not separable from the Strom- 

 bus pugilis of Carrick Moore and myself. One of Sowerby's names 

 (being prior) must therefore take the place of my name pugiloides ; 

 and the name proximus may be allowed, to indicate the position of 

 the species so near to the recent S. pugilis. 



31. Strombits bifrons, Sow. G. J. vol. vi. p. 48, pi. ix. fig. 9. 



I prefer to retain this name for the specimens which resemble 

 Strombus dilatatus and columba more than jmgil is. 



32. Murex bomixgensis, Sow. G. J. vol. vi. p. 49, pi. x. fig. 5. 



Gabb notes the relationship of the species to M. liaustellum. To 

 my eye its nearest kindred is M. messorius, Sow., a West-Indian 

 recent species by no means very close to M. liaustellum. 



I cannot decide if M. ant ilia rum, Gabb, is distinct from M. 

 domingensis, Sow. 



33. Murex cornerectes, n. sp. (PI. XXYIII. fig. 4.) 



Ovate-turreted, with three varices, which are nearly continuous, 

 and stout revolving ridges accompanied by finer lines ; two or 

 occasionally three variciform tubercles between each varix ; varices 

 fringed by subtubular spines, of which the one corresponding to the 

 'keel on the angle of the whorls is much the longest. Aperture oval, 

 the inner margin callous, the outer margin dentate, the dentations 

 running in pairs. Canal moderately long and slightly curved.
