SAUROPTERYGIA. 
Plesiosaur va. 
*? Plesiosaurus sp. Tooth. Lower Zrigonia-Grit (discite). Bajocian. 
Frith Quarry, near Stroud. 
Professor §. H. Reynolds and Dr. C. W. Andrews both state that this tooth 
is ‘* Plesiosaurian in type’’. 
*? Pliosaurus sp. Two teeth. Top of Lower Zrigonia-Grit or bottom 
of Buckmani-Grit (diseite). Bajocian. 
Professor §. H. Reynolds states that these teeth ‘‘are exactly lke 
Pliosaurian teeth in the British Museum ’’—an identification confirmed by 
Dr. C. W. Andrews. 
A piece of bone 6 inches long was obtained from the Gryphite-Grit

PISCES. 
ELASMOBBANCHEI. 
Selachit. 
Asteracanthus. See Strophodus. 
Strophodus. General Note.—The teeth called Strophodus include two 
species: one in which the crown is flat (S. magnus, Ag.), and the 
other in which it is considerably elevated, and the tooth itself 
long and narrow (S. tenuis, Ag.). Satisfactory figures of these 
species will be found in the Catalogue of the Fossil Fishes in 
the British Museum, pt. i (1889), pl. xv, figs. 2, 3, and 4-8. 
The teeth which have been named S. retcculatus are now definitely 
known to belong to Asteracanthus ornatissimus, Ag., and are very 
differently ornamented and keeled.

Myriacanthus sp. Fragments of palatine teeth. Identified by Dr. A. 
Smith Woodward. Inferior-Oolite. Cleeve Hill, near Cheltenham. 
Remains of this genus of Chimeroid fish have not been recorded before from 
the Middle Jurassic: ouly from the Lias and Kimmeridgian (vide Dr. A. 
Smith Woodward, Quart. Journ. Geol. Soc., vol. lxii, 1906, pp. 1-4, and pl. i; 
Brit. Mus. Cat. Fossil Fishes, pt. ii, 1891, p. 48). Unfortunately the 
fragments from Cleeve Hill were not found in sitz.
