BIBLIOGRAPHY OF PALAWOZOIC CRUSTACBA 127 
WALCOTT (Charles D.)—Continued 
Walcott refers Dikelocephalus misa Hall to this genus. ‘Che other species referred by 
Brégger to the genus, such as Dikelocephalus osceola Wall, are referred by Walcott to 
a new genus Osceolia, and Dikelocephalus spiniger to the new genus Calvinella. 
3. Saukia, new genus. The genus has a narrow frontal border about the cephalon, 
and a glabella proportionately more elongated than in Dikelocephalus. ‘The pygidium 
is less expanded and more elongate than that of Dikelocephalus. Genotype Dikelo- 
cephalus lodensis Whitt. 
The author describes Saukia coloradoensis n. sp. 8S. crassimarginata Whitfield, 1882, 
S. fallax n. sp., junia n. sp. 8. leptaenarum Wiman, 1907; S. leucosia n. sp. 8S. lodensis 
Whitf. the type S. marica Walc., 1886; 8. pepinensis Owen, 1852; S. pyrene n. sp., S. 
rustica n. sp. S. stosei n. sp., S. wardi n. sp. 
4. Osceolia, new genus. ‘Chis genus is characterized by its concave. frontal limb, 
palpebral lobes, narrow fixed cheeks and transverse pygidium with its anterior segment 
extended beyond the margin as a long spine. Genotype Dikelocephalus oseola Hall, 
1863. 
5. Calvinella, new genus. Genotype Dikelocephaius spiniger Hall, 1863. This genus 
is like Saukia, but differs in form of the glabella, presence of strong occipital spine, and 
proportionally more elongated pygidium. It differs from Osceola*in frontal limb of 
cephalon, presence of occipital spine and character of pygidium. 
The author refers to the genus Dikelocephalus newtonensis Weller, 1903; Calvinella 
ozarkensis n. sp. Dikelocephalus spiniger Wall, 1863, and Calvinella tenuisculpta n. sp.

The author gives a historical review with a summary of the genera and species. 
A new genus, T’sinania, with ///aenurus canen for the genotype, is given on page 43. 
The genus differs from Ilaenurus Hall, in having the cranidium rounded in front, by 
the incurving of the facial sutures, and short postero-lateral limbs. He refers several 
species to the new genus previously included under Hall’s genus, viz: T’sinania canens, 
L,. Ceras; 1, cleora-and 1, dictys.

The author, under the Order Proparia, describes several new genera. 
Family Menomonidae—Menomonia a new genus with Cozocephalites, calymenoides 
Whitfield as the genotype. 
Millardia, a new genus with MM. semele as genotype. Refers one new species M. 
avitas and Conocephalites optata Hall, also, to the genus. 
Dresbachia, a new genus with D. anata as the genotype. 
Norwoodide, a new family with a new genus, Norwoodia, with five new species: 
Saffordi, N. simplex and N. tenera. 
Genotype N. gracilis, also N. ponderosa, N. 
The cranidium, with its Ptychoparia-like glabella and small eyes and broad pleural 
furrows, are primitive, while the few thoracic segments (8 or 9) and relatively large 
tail, suggests the sub-family Phacopinae. Under the order Opisthoparia, he describes 
Agraulos stator n. sp.; also Acrocephalites Wallerus, with a translation of that au- 
thor’s description of the genus, with nine new species. Refers Solenopleura 2 stenome- 
topa Ang. and Conocephalites vulcanus Bill, to the genus. 
Compares the new species 4. Haynesi and tutus with the genotype, Acrocephalites 
insignis has narrower fixed cheek and frontal limb of 4. stenometopus, 4. Americanus
