BIBLIOGRAPHY OF PALASOZOIC CRUSTACEA 20 
Cobbold (fH. 8.) On some small Trilobites from the Cambrian Rocks 
of Comley, Shropshire. 
Quart. Jour, Geol. Soc., vol. 66, No. 261, pp. 19-50, plates 3-8. 
Microdiscus comleyensis n. sp. 
This species appears to be somewhat intermediate between M. speciosus Ford and 
M. punctatus Salter, but only has % annulations in the axis of the pygidium. 
Microdiscus lobatus Hall, M. Helena Walcott, M. speciosus Ford. Ptychoparia ? 
Attleboroughensis Sh, and F., P.2 annio n. sp. Micmacca ? ellipsocephaloides n. sp. cf., M. 
recurva Matthew. M. ellipsocephaloides var. Spinora and var. strenuelloides and var. 
senior, M. ? parvula n. sp. Agraulos (Strenuella) salopiensis n. sp. Anomacare platyce- 
phalum n, sp, A. parvum n. sp., A. 2 pustulatum n. sp. Protolenus latouchei n. sp., P. 
morpheus n. sp. Mohicana un. gen. 
This new genus has characters very similar to those of Micmacca ? plana Matthew, 
which that author referred provisionally to his genus. 
Mohicana lata n. sp.. M. clavata n. sp. 
The author remarks these two species have many points of resemblance with 
Micmacca ? plana Matthew, also with Avalonia manuelensis Walcott; but the peculiar 
eroove on the line of the ocular ridge are absent, and the frontal limb is more extended.

Quart. Jour. Geol. Soc. London, vol. 67, No. 267, 1911, pp. 282-311, plates 23-26. 
The author describes Paradoxides Groomi Lapworth from the type specimen, and 
figures it for the first time; also Paradoxides sp. indet., P. Davidis Salter, P. rugulosus 
Corda. Conocoryphe emarginata Linnarsson yar. longifrons nov. Dorypyge Lakei sp. 
noy. ‘This species is nearly allied to the pygidae of Dorypyge oriens Gronwall. 
The species might be compared with Dikellocephalus Marcoui (Whitfield) from 
Georgia, Vermont; see, also, Walcott’s figures of this species. 
A gnostus fallax Linnarsson, Microdiscus sp. cf. M. punctatus Salter. A graulos holo- 
cephalus Matth., 4. sp. cf. 4. quadrangularis Whitt. 
The author follows Reed’s classification of the genus Ptychoparia Corda, and places 
the genera Ptychoparia Liostracus and Conocephalites, under subgenera to Ptychoparia. 
The author describes Ptychoparia (Liostracus) pulchella sp. nov., nearly related to 
Liostracus validus Matth. and L. Linnarssoni Brogger, but differ from both in the rela- 
tive length of the glabella. Ptychoparia (Liostracus) sp. ident. two forms and P. (Lios- 
tracus) dubia sp. nov. 
—— The Trilobite fauna of the Comley Breccia-Bed, Shropshire. 
Quart. Jour. Geol. Soc., vol. 59, No. 273, pp. 27-50, plates 2 and 3, 
The author describes and illustrates Paradoxides intermedius nov, 
The species differs but slightly from P. Hicksii, its var. palpebrosus Linnarsson and 
P. Sjégreni in the course of the facial suture and general form. 
Agraulos sp. cf., 4. Quadrangularis Whitheld. Subgenus Strenuella (A graulos) sp. 
indet. Conocoryphe aequalis Linnrs. C. bufo Hicks. subgenus Liocephalus impressa 
Linnrs. Dorypyge reticulata nov. 
The cranidia of D. Laket is very much like the new species, but the thorax and 
pygidia are different, and the reticulate character of the test very distinctive.
