256 On the Land and Freshwater Shells of Barbados. 



This species is allied to, but not quite the same as, T. hila- 

 hiata, Pfr., from Cuba.

Hah. Barbados (in coll. Cuming). 



In Sowerby 's figures the spire is represented a little too 

 elevated and acuminate. The figures in the ' Conchologia 

 Iconica ' (figs. 49 a, Z»),as pointed out by Bland (Jouvn. dc 

 Conch. 1875, p. 247), are altogether incorrect. 



28*. Fhysa rivalis^ ]\Iaton & Rackett. 



Bulla rivalis, Maton and Kackett, Trans. Linn. Soc. 1807, vol. viii. 



p. 120, pi. iv. fig. 2. 

 Lininca (Phi/sa) rivalis, Sowerby, Genera Shells, pi. clxxix. fig. 0. 



Hah. Brazil, Cuba, St. Vincents, Trinidad, &c. 



This species is said by Jeffreys and otliers to be the same 

 as Soirerbyana of d'Orbigny. This is probably the case, and 

 P. acuminata, Gray, is also identical. 



P. rivalis of the ' Conchologia Iconica ' (fig. 31) is not this 

 species, and is at once separated by the reddish thickening 

 within the margin of the outer lip, which does not exist in 

 the true P. rivalis.
