| Scolecoderma, Salter. The tubes of mud-loving 
annelides are thin and membranous usually. 
(S. dispar, Salter, is a true Serpulites.) 
[Turrilepas, H. Woodward. Shelly plates ar- 
ranged in four rows, unsymmetrical, cari- 
nated, and imbricated, with a uniformly 
sculptured surface, destitute of lateral pro- 
cesses. Considered to be related to Lori- 
cula, Scalpellum, and other pedunculated 
cirripeds. 
Mr Salter considered it an Annelide 
tube, shelly, of numerous plates imbricating 
backwards, and proposed the name Oplo- 
scolex for it. Hdiior.]

metropolis of the Trilobite group, there are 
a good many genera (all, with two excep- 
tions, the same as Cambrian) and the species 
and individuals are very numerous in 
Wenlock and Dudley strata. Small Phyllo- 
pods and large shrimp-like forms (Ceratio- 
caris) begin to be abundant and numerous 
in species. 

Ceratiocaris, sp. The genus will be more 
fully described in the Ludlow rocks, and 
it is doubtful if this one be of Wenlock 
age. 
Beyrichia Kloedeni, McCoy. (Ann. N. Hist. 
2 ser. Vol. xvi. pl. 6, figs. 7—9). The genus 
is a most natural and convenient one for 
those small-lobed and tubercled bivalve 
crustacea which it represents.
