Puychoparia ? cilles nov. P. pylas noy., from Gordon Creek, Montana. 
Crepicephalus chares nov., related to C. camiro. 
Vanuxemella nortia Walc. Olenopsis cf. Americanus Walc. 
Albertella Bosworthi Walc., 4. Helena Walc., 4. levis nov. 
Zacanthoides charilla nov. compares Z. idahoensis Z.? cimon nov., Z. cnopus nov., 
the thorax has the great median spine on the 8th segment instead of the Sth as in Z. 
Idahoensis. 
Neolenus constans nov. 
Bathyuriscus Rossensis nov., characterized by the very mich produced genal spines 
extending backwards to the pygidium. 
Bathyuriscus cf. Rossensis nov. The glabella is longer and more slender proportionally 
than that of Rossensis. 
but differs in many details. 
Bathyuriscus (Poliella) chilo nov. 
Differs from B. (P.) sylla of the Chetang formation in the nearly straight sides of 
the glabella, and narrower and shorter associated pygidium. Related to B. (P.) primus,

A gnostus laevigatus Dalm. also var. armata Linrs., Ad. exsculptus Ang., also forma 
sulcifera, integra, Agnostus planicauda Ang.; also forma vestgothica, A. pisiformis

Conocephalus suecicus n. sp. 
Acrocephalites stenometopus n. gen. for Angelin’s Solenopleura ? stenometopus. 
It is characterized by a suture running inwards to the rim of the head shield in front 
of the eyes, a pointed front to this shield, and a small knob in front of the glabella. 
Liostracus costatus Ang. Proceratopyge conifrons n. gen. et sp. This genus, as its 
name indicates, is the typical species of the Ceratopyge. It differs in its conical gla- 
bella, its four pairs of glabella furrows and the triangular front fold of the rim. 
Toxotis pusilla n. gen. et sp. This is a remarkable genus, which retains several 
embryonic or early larval characters, as the narrow glabella, and three swellings on the 
front of the shield.
