Giffoni, Province of Salerno, Italy. This is the caudal 
half of a fish as small as P. pusillus , but apparently with

P. 566. Type specimen of the so-called genus and species Nothosomus 
octostychius (Agassiz, Poiss. Poss. vol. ii. pt. i. 1844, p. 292, 
name only), described by Egerton, Pigs. & Descript. Brit. 
Organic Remains, dec. ix. (Mem. Geol. Surv. 1858), no. 6, 
pi. vi.; Lower Lias, Street, Somersetshire. This appears 
to be a deep-bodied species of Pholidophorus with unusually 
thick scales, but its systematic position cannot be deter¬ 
mined until the discovery of the head. Egerton Coll.
