524 R. J. L. GUPPY ON THE MIOCENE EOSSILS OF HAITI. 



whether they ought to be so regarded, though unquestionably nearly 

 allied. A reexamination of the Haitian fossil revealed to me some 

 difference in the surface characters of the Miocene and recent shells.

Fusiis henelceni, Sow. G. J. vol. vi. p. 49. 



An examination of Sowerby's F. haitensis proves that it is only 

 an individual form of F. henekeni. Similar variations occur in the 

 recent analogue of the species, F. distans, Lam.

This shell is well represented in the Geological Society's collection.

53. Phos elegans, Guppy, G. J. vol. xxii. p. 290, pi. xvi. fig. 13. 



Gabb makes this a synonym of P. verdguensis, Hinds, which I am 

 not prepared at present to indorse ; but I concur with him in re- 

 garding P. Moorei as a form of P. clegans. I should go a step 

 further and unite, under the name of P. elegans, the forms described 

 by Gabb as P. costatus and P. semicostatus. The JS 7 assa solidida of 

 the West-Indian Miocene appears to be distinct ; but it is not re- 

 corded from Haiti.

55. Clea truxcata, Gabb. (PI. XXIX. fig. 6.) 



Ectracheliza truncate, Gabb, Proc. Acad. 1ST. 8. Phil. 1872, p. 271, 

 pi. ix. fig. 2 ; Trans. Amer. Phil. Soc. vol. xv. p. 213. 



The new genus Ectrachc-liza, described by Gabb, appears to me 

 identical with Clea, Adams, of which the type Clea nigricans, Adams, 

 was figured in Gen. Moll. vol. ii. p. 625, pi. exxxvii. fig. 8. The 

 two species agree in general form, in the truncation of the apex, and 

 even in the jnesence of an impressed more or less double spiral line 

 below the suture. The fossil C. truncate appears to differ from the 

 recent C. nigricans chiefly in the following respects : — The latter has 

 a more vertical aperture, the outer lip not being so prominent an- 

 teriorly ; and its columella is rather more strongly twisted. 



The genus is with little doubt closely related to Planaxis, forming 

 one of the links of connexion between Oliva and the other members 

 of the Buccinidte. Another species which may be compared with 

 Clea truncate is the Quoyia decollata of Gray (Peeve, El. Conch, 

 vol. i. p. 63, pi. iii. fig. 18), which, besides other differences, has a 

 considerably higher spire.
