Gen. Conchyliolithus. Fam. Anomita;. 
Sedes : strata vetusta, calcaria. Matrix sape petrosilex. 
Common. 
Obs. This is one of the imperforate anomitie, with an internal structure similar to that observad 
m giganteus. In V. 1. this structure has imparted to the surface of the fossil, near the beak, a 
small trilobate gibbosity, which is not found in a. 
punctatus. rj. Conch. Anomites subrotundatus transversim striatus: striis remotis; in- 
terstitiis punctatis, valva altera gibbosa, cardine subcurto.

Dotted Anomite. 
Sedes : strata vetusta, calcaria. 
Common near Chelmerton. 
Obs. In V. a. the dots or punctures, between the striae, are numerous, crouded, and without 
order ; in h. few, distant, and disposed in two or three series. From recent observation, we are 
inclined to, consider these dots as the bases of minute, slender spines, with which the original was 
armed, but which are seldom, if ever, visible in the fossil. 
aculeatiis. 8. Conch. Anomites subrotundus, valva concava laevi, altera^gibbosa retror- 
sum aculeata : aculeis raris adpressis brevissimis, cardine subcurto.

Prickly Anomite. 
Sedes : strata vetusta, calcaria, et raro vens metallifera. 
In the limestone strata near Bakewell, Buxton, ike. We have also 
lately observed it in clay accompanying lead-ore, in some veins near Mid- 
dleton; bur, like all other real petrifactions, it must be considered as very 
rare in such a situation. 
scabriculus. 9- Conch. Anomites subrotundus, valva plana obsolete punctato-striata, 
altera gibbosa : striis elevatis longitudinalibus tuberculatis ; tuberculis 
oblongis subquincuncialibus.
