An imperfect jaw of Pacliyrliizodus from the Turonian (Planer- 
kalk) of Strehlen, Dresden, is described under the name of Hypsodon 
lewesiensis.) Ag., by H. B. Geinitz, Palaeoutogr. vol. xx. pt. ii. (1875), 
p. 222, pi. xliii. fig. 1. 
A renewed examination of the type specimen of Mosasaurus 
gracilis, Owen, from the Chalk of Sussex, in the Brighton Museum, 
has convinced the present writer that the fossil is truly part of the 
mandible of a Mosasaurian. It was therefore wrongly named 
Pacliyrliizodus gracilis in A. S. Woodward, Proc. Geol. Assoc, 
vol. X. (1888), p. 314. 
The genera and species described as follows are supposed to be 
related to Pacliyrliizodus, but are too imperfectly known for precise 
determination. They are not represented in the Collection :—
