670 C. CALLAWAY ON A NEW AKEA OF UPPER 



fection for satisfactory determination. It is very crinoid-like in its 

 long, slender stem, and its circle of arms, which, however, appear 

 to be only simple pinnulse. 



Maceocystella Makle, n. sp. (Plate XXIY. fig. 13.) 



Some of the best specimens were collected by Mr. Bird. 

 The Shineton Shales at Shineton, and nnder Cound-Moor quarry. 

 Not rare. 



Dexdrogbapttjs, Hall. 



Dendeogeaptus, sp. 



I am not prepared to assign the Shineton specimens to any known 

 species, or to give them a new name ; and several graptolithologists 

 to whom I have submitted them differ from each other in their de- 

 terminations. All are found in Mary Dingle, associated with Obo- 

 lella, Lingulella, and Platypeltis, on a lower horizon than the bulk of 

 the Shineton fauna. 



DlCTYONEMA, Hall. 



u * 



Dictyonema sociale, Salter. 



Good specimens of this common North-Wales species are found 

 in abundance in the Shineton Shales at Pedwardine and south of 

 Malvern. 



Kutoegina, Billings. 



Ktjtoegixa cingtjlata, Bill. 



Kutorgina cingulata, Bill. Geol. Surv. Canada, Pal. Foss. vol. i. 

 pp. 8-10. 



This form is found in the Potsdam Sandstone of North America, 

 the probable equivalent of our Lingula-flags, or of a still lower 

 group. The Obolella PMltypsii, Hall, of the Hollybush Sandstone of 

 Malvern, is identified hv Mr. Davidson with Billings's species. I 

 have collected it in abundance in the Hollybush Sandstone at Neves 

 Castle, at the south-west end of the Wrekin, and have also detected 

 it near Lawrence Hill. The specimens collected will throw some 

 light upon the characters of this comparatively unknown genus ; 

 but I defer further discussion until I have obtained more satisfac- 

 tory material.
