54 ONYCHIOPSIS. 
V. 2616. Under this number there are two specimens of a 
coarser form of O. Mantelli. Sussex. Beckles Coll. 
7354. Two small specimens (one without a registered number, 
but probably the reverse of 7354), which closely resemble some 
fragments figured by Mantell' and Brongniart.? Tilgate Forest. 
Mantell Coll. 
8390. This agrees closely with Mantell, Joc. cit. pl. xx. fig. 2, 
and Brongniart, doc. cit. pl. xlv. fig. 7a. It is possible that the 
figured specimen was the reverse piece of the Museum example. 
Tilgate Forest. Mantell Coll. 
32593. Shows a prominent rachis projecting from the surface 
of the sandstone. ‘Tilgate Forest. Mantell Coll. 
38367. Part of a pinna. This specimen bears a certain resem- 
blance to that figured by Stokes and Webb,? pl. xlvi. fig. 7, and 
reproduced in Mantell’s ‘‘ Geol. S.E. England,” and in Brongniart’s 
‘* Hist. vég. foss.”’ There are, however, distinct differences 
between the specimen and the figures referred to, which compel 
me to merely suggest the possibility of the Museum specimen 
being the reverse piece of Stokes and Webb’s original. Tilgate 
Forest. Mantell Coll. 
38372. In all probability this is the type specimen of Mantell’s 
Sphenopteris Sillimani, figured in the ‘Geol. S.E. England,” 
p. 239. Hastings Sands, Sussex. Mantell Coll.
