The new species Encrinurus Indianensis of the Niagara Group has a semi-circular 
cephalon, test tuberculated, Glabella with 3 strong tubercles on each side, anterior 
to the occipital groove; fixed cheeks separated from the glabella by deep dorsal grooves; 
genal angles spined; pygidium elongated, triangular, convex; axis 15 joints; lateral 
ribs 10. Each ring of the axis has 3-5 tubercles, the median one being the strongest.

The author notes and illustrates the following Crustacea: 
Phacops rana Green, P. cristata Hall, with var. pipa Hall. Cryphaeus cf. Boothi 
var. calliteles (Kayser). Dalmanites (Coronura) aspectans Conrad. Odontocephalus 
selenurus (Eaton), O. aegeria Hall. Phaethonides gemmacus H. & C. Conolichas cf. 
hispidus H. & C. Cyphaspis cf. stephanophora H. & C. Lichas (Arges) contusus H. & 
C, var. Acidaspis callicera H. & C. Dalmanites sp. wndet. 
Ostracoda: Bollia ungula Jones, B. obesa Ulrich. Bythocypris favulosa Jones. 
Ulrichia conrandi Jones. Octonaria stigmata Ulrich. Leperditia cf. subrotunda Ulrich. 
The above list of 13 species contains three trilobites known in the Hamilton fauna. 
One, Phaethonides gemmaeus, is common to the Onondaga and Hamilton faunas in 
New York. ‘The doubtful species (Cryphaeus cf. boothi var. callites) has an occur- 
rence at a horizon, earlier than the Hamilton now first reported. ‘The third Phacops | 
rana is one of the very few Devonian trilobites having a wide range.

The author remarks, on p. 34: “Not a single homology can be drawn with any t 
degree of certainty between Limulus and any trilobite. The regional divisions are 
different; the appendages are built upon a different plan, while the larvae of the two 
groups present but the slightest and most superficial resemblance to each other.”
