This differs from the figure of P. plicosa (Bronn, Leth. Geogn. 

 taf. 40. f. 24) in having only three plicae, one large and two small. 

 1 . Trichotropis borealis, Lowe (Zool. Journ. Fusus umbilicatus, Smith, 

 Mem. of Wernerian Nat. Hist. Soc. vol. viii. p. 50. fol. 1. f. 2).

1. Macromphalus reticulatus.

Gen. Char. Shell fusiform ; spire elevated ; aperture ovate ; outer 

 lip sharp ; umbilicus linear. 



Spec. Char. Shell fusiform ; volutions convex ; suture deep ; sur- 

 face reticulate ; aperture ovate ; peritreme sharp, continuous ; um- 

 bilicus linear, striate. Axis one-fourth of an inch. PI. V. f. 16. 



The lengthened form of the umbilicus has suggested the name 

 proposed for the genus. 

 Sect. a. dextral.

I presume this to be identical ; the lower part corresponds, but the 

 apex of the crag shell is obtuse, and the two first volutions possess 

 longitudinal costse. This portion is not shown in the figure above 

 referred to. 



3. — tuberculare (Murex tubercularis, Mont. Test. Brit. p. 270).
