BIBLIOGRAPHY OF PALASOZOIC CRUSTACEA 129 
WALCOTT (Charles D.)—Continued 
Salteri 2? Rominger, which he refers to Karlia Stephensis, Dr. Matthew, 1899, refers 
the genus to Dorypyge, and the species to Dorypyge Daacsoni. 
The author describes a new genus Hanburia with its genotype HH. gloriosa. Remarks 
the large pygidium and few thoracic segments suggest the order: Opisthoparia and 
family Asaphidae. From Burgess Pass above Field, B. C. 
Under Tsinania, the I//aenurus canens Walc., as the genotype, Walcott, includes the 
new species 7. cleora and T. elongata.

The author describes and illustrates the following Cambrian ‘Trilobites: 
Corynexochus bornholmiensis Gronwall, C. brennus Wale. C. bubaris Wale. C. 
capito Wale., C. clavatus Walc., C. delage: Miquel.. C. minor, C. senectus (Billings), 
GC. spinulosus Ang., C. stephenensis (Walc.). 
Refers Corynexochus romingeri Matt. to C. stephensis, Corynexochus 2 umbonatus 
Angelin to the genus A°%glina. 
The new subgenus Bonnia is proposed as a subgenus to Corynexochus, with Bathy- 
urus parvulus as the genotype. 
The author includes Corynexochus (Bonnia) busa nov., C. (Bonnia) fieldensis, the 
Protypus fieldensis Walcot, 1908. 
Corynexochus (Bonnia) parvulus the Bathyurus parvulus Billings, 1861. 
Sub-family Dolichometopinae. 
Bathyuriscus adaeus nov. B. anax nov.

ING. 30; ph 30; tig, 1, la) 1b, ig and 1h. 
Bathyuriscus atossa nov., B. bantius noy., B. batis nov., B. belesis nov., B. belus nov.,

ornatus Wale. B. rotundatus Rominger, B. Stoliczkai Reed, B. sp. undetermined, Nos. 1 
and 2, 
Bathyuriscus (Poliella) new subgenus. 
Most of the species of Poliella are small, with from seven thoracic segments to 
eleven segments and a small pygidium. 
The genotype Bathyuriscus (Poliella) anteros Walcott. 
The author includes eight species under the subgenus: Bathyuriscus (Poliella) anteros 
nov., B. (P.) powersi, B. (P.)occidentalis nov., B. (P.) primus, B. (P.) caranus nov., 
Bee Jtvild, B..( Pa) Pals Nov. Bb. (P.) probis. 
Dolichometopus. 
Dr. Walcott refers eleven species to this genus: Dolichometopus acadicus Matt. D. ? 
alceste Walc., D. baton Walc., D. ? bessus Walc., D. bion Walc., D. boccar Wale., D. ? 
deois Walc., D. ? derceto Walc., D. ? dirce Walc., D. ? expansus (Walc.), D. productus 
(H. & W.), D. suecicus Ang., D. tontoensis Wale. 
The other species of Dolichometopus, such as Dolichometopus ? convexus Billings, 
referred to Bolbocephalus, D. ? gibberulus Bill. to Platycolpus, D. hyie Walec., to 
Anomocare, D. occidentalis Matt. to Bathyuriscus, D. ? rarus Bill, to Bolbocephalus, 
D. tatei Woodw. to Redlichia. 
The author forms a new subgenus, for certain species with a small palpebral lobe, 
that lack genal spines on the free cheek, with Dolichometops (Housia) varro Walcott 
as the genotype. 
Family Asaphidae, sub-family Ogygiocarinae.
