[^Piruldf Lam.] The three allied, so-called, genera Pulgur (Montf.), 
Siycotypus (Rrowne), and Tudicta (Link), are reviewed by Ta. Gitn, and all 
the Species known enumerated. The recent ones are Putguf carted (Gmel.), 
perversa (L.), coarciata (Sow.), ttll from the east coast of North America 
[and Gulf of Mexico], Sycoiypus canaliculatus (L.) ^udipyrum (Hillw.), With 
the same geographical distribution. Some other Species occur in the miocene 
beds of Carolina aud Maryland. Tudicla has only one species, spirilhi^ (L.) | 
the nearly allied Fasciotarid potphyrosioind (Ad. et ReevC) Should be re- 
garded fts the type of ft new genus, Sireptosipkoii. Am. JottrU. Conch, lii.

T. A. Co^tUAI) gives also a review of the species of Sycatypus and 
BiUycon, observing that the distinctive characters, although apparent in the 
recent species, do not hold good for miocene shells. He enumerates the 
recent Species as follows ; — Sycoiypus dattaUdutatm (L.), S. ptagksus (Conrad), 
•with a variety, elcgans (Conrad), ftnd S. pyrufn (J^^A^.^^Fulgur pyruloideB
