Vol. 67.] FROM THE PARADOXIDES BEDS OF COMLET. 307 



Fig. G. Thoracic segment [1307] : a, seen from above ; b, section transverse 

 to tbe thorax. 



7. Median pleura [B 12 ] : a, seen from above ; b, section near the middle 



of the length of the pleura ; c, cross-section at the fracture. 



8. One of the posterior pleura? [1308] : a, seen from above ; b, cross- 



section at the fracture. 



9. Part of pygidium [A-] : a, seen from above ; b, transverse section. The 



posterior rounded outline is added from another specimen [A G ], the 

 anterior margins are hypothetical. 

 10. Hypostoma, cast of interior [B,]. The narrow posterior border is 

 missing in the specimen, but appears in the external cast [C\], which 

 also shows the length along the axial line. 

 [Except figs. 6 and 8, all the specimens are in the Lapworth Collection.] 



Plate XXIV. 



[Where no degree of enlargement is stated, the figures are of the 

 natural size.] 



Paradoxides sp. indet. No. 1. Comley Quarry. (See p. 285.) 



Fig. 1. Part of glabella and front [1317 a]. 



2. Free cheek [A 470, H. C. B., PJ, Mr. Beasley's Collection. 



Paradoxidcs sp. indet. No. 2. Comley Quarry. *(S>ee p, 285.) 



Fig. 3. Part of glabella and fixed cheek [1314]. 



4. Fixed cheek and postero-lateral border [1307 «]. 



5. Part of glabella and fixed cheek [1317 b~\. 



6. Pygidium [1171] .' a, seen from above; b, from behind ; c, from above, 



X 3; d, from the side, X 3 ; e, portion of posterior border much 

 enlarged. 



Paradoxides sp. indet. No. 3. Comley Quarry. (See p. 285.) 



Fig. 7. Pygidium, Lapworth Collection : a, seen from above ; b, from the side ; 

 c, from behind. 



Conocoryphe emarginata Linnrs., var. longifrons, nov. Comley Quarry. 



Fig. 8. Cranidium, seen from above [1317 c]. (See p. 286.) 



9. Pygidium, probably of this species [A 470, H. C. B., CJ : a, seen from 

 above ; b, from the side ; c, from behind ; all X 3. Drawn from a 

 plasticine mould of an external cast in Mr. Beasley's Collection. 



10. Free cheek, referred with doubt to this species [1344], X 3. 



11. Another specimen, seen from below [1345], X 3. 



12. Internal cast of cranidium [204] : a, seen from above ; b, from the 



side ; c, from behind ; all X 3. 



13. Internal cast of front and fixed cheek [1341], X 3. This represents 



the specimen as viewed from a direction normal to its transverse 

 curvature, and not from above the complete cranidium. Tbe cheek 

 appears therefore proportionately wider than in the previous figure. 



Paradoxides rugulosus Corda. Shoot-Eough-Koad Sandstone, Comley. 



Fig. 14. Outline of two very fragile internal casts of cranidia [1180] ; the 

 specimen is now much damaged. (See p. 286.) 



15. Glabella and front [1073]: a, seen from above; b, from the side; 



both x 3. 



16. Pygidium [1082] : a, seen from above ; b, from the side ; c, from behind; 



all X 3. 



Paradoxides davidis Salt. Shoot-Bough-Eoad Flags, Comley. (See p. 285.)

 18. Pygidium, younger form [321] ; seen from above.
