22. 2. STICTOPORA GLOMERATA (». sp.). 
Pl. IV. Fig. 5. 
The specimen consists of a surface several inches square, covered and crowded with this 
coral, denuded completely of its celluliferous crust. Its appearance is very similar to the 
specimen fig. 4 e, though its mode of growth is considerably different; and principally from 
this circumstance, as well as from the impossibility of defining the external characters of 
the coral, I have referred it, with some hesitation, to a distinct species. 
Position and locality. Granville (Vermont), in a limestone, associated with Maclurea 
magna, which I have elsewhere shown to be identical with that of Chazy. 
Genus STREPTOPLASMA ( Fam. Cyathophyllidea ). 
[ Greek, Grpsirros, twisted, and wXatfjxa, lamella?.] 
Turbinate, gradually or abruptly expanding above; form like Cyathophyllum ; terminal 
cup more or less deep ; lamellae vertical or longitudinal, more or less spirally twisted 
together when meeting in the centre. 
There is some objection to the application of the term Strombodes of Schweigger to 
fossils of this character, or those formerly grouped with Cyathophylla 2 , as the genus was 
constituted for a different coral. To indicate the prominent character, I have proposed this 
name as applicable to a considerable number of palaeozoic species. 
23. 1. STREPTOPLASMA EXP ANSA (n. sp.). 
Pl. IV. Figs. G a, b. 
Turbinate, short, expanding above ; terminal cup deep ; lamellae fine, numerous. 
This species presents some variety of form and aspect, but its essential characters are a 
short broad turbinate form, with a deep cell. It is imbedded in the crystalline encrinital 
limestone, and being itself usually in a crystalline state, it appears like the pelvis of a 
crinoidean. From this crystalline condition, nothing satisfactory can usually be learned 
respecting its structure. 
Position and locality. This species is apparently confined to the lower part of the Chazy 
limestone, not having been noticed above the position of the Maclurea magna. It abounds 
at Chazy, to the west and southwest of the village. {State Collection.)
