WALCOTT (Charles D .)— Continued 



Salteri ?Rom\ng,er, which he refers to Knrl'ui Stcplirnsis. Dr. Matthew, 1899, refers 

 the genus to Dorypyge, and the species to Dorypyi^e Dazisoni. 



The author describes a new genus Hanburia with its genotype //. ^^loriosa. Retnarks 

 the large pygidium and few thoracic segments suggest the order Opisthoparia and 

 family Asaphidae. From Burgess Pass above Field, B. C. 



Under Tsinania, the Illoernirus (aneris \\'alc., as the genot\ pe, W'alcott, includes tiie 

 new species T. drora and T. elotiifafa.

Refers Corynexochus rotnitiireri Matt, to (\ stepliensis, Cnryncxuihiis ? umbonatiis 

 Angelin to the genus ^'Eglina. 



The new subgenus Bonnia is proposed as a subgenus to Corynexochus, with Bal/iy- 

 iinis par-vulns as the genotype. 



The author includes Corynexochus (Bonnia) htisa nov., ('. (Bonniii) ficlJcnsis, the 

 Protypus fieldensis Walcot, 1908. 



Corynexochus (Bonnia) par-vulus the Bathyurus ptirvulus Billings, 1S61. 



Sub-family Dolichometopinae. 



Bathyuriscus adaeus nov., B. anax nov.

 ornatus Wale, B. rotundatus Roniinger, B. Stoliczkai Reed, B. sp. undetermined, Nos. 1 

 and 2. 



Bathyuriscus (Poliella) new subgenus. 



Most of the species of Poliella are small, with from se\en thoracic segments to 

 eleven segments and a small pygidium. 



The genotype Bathyuriscus (Poliella) anteros Walcott. 



The author includes eight species under the subgenus: Bathyuriscus (Polirlta) anteros 

 nov., B. (P.) po^cersi, B. (P.)occidentalis nov., B. (P.) primus, li. (P.) caranus nov., 

 B. (P.) sylla, B. (P.) balus nov., B. (P.) probus. 



Dolichometopus. 



Dr. \\'alcott refers eleven species to this genus: Dolichometopus acadicus Matt.. D. ? 

 alceste Wale, D. baton Wale, D. f bessus Wale, D. bion Wale, I), boccur Wale, D. ? 

 deois Wale, D. ? derceto Wale, D. ? dirce Wale, D. Z expansus (Wale), I), productus 

 (II. & W.), I), suecicus Ang., D. tontoensis Wale 



The other species of Dolichometopus, such as Dolichometopus ? con-vexus Billings, 

 referred to Bolbocephalus, D. ? i^ibberulus Bill., to Platycolpus, D. hyie Wale, to 

 Anomocare, D. occidentalis Matt, to Bath\ uriscus, D. .^ rams Bill, to Bolbocephalus, 



D. tatei Woodw. to Redlichia. 



The author forms a new subgenus, for certain species with a sinall palpebral lobe, 

 that lack genal spines on the free cheek, with Dolichomrtops (llousio) zuirro Wnlcott 

 as the genotype. 



Family Asaphidae, sub-family Ogygiocarinae.
