SUPPLEMENT— PAQU1ERIA. 



lxvii 



Distinction. — From Kiliania, greater compression, the brevi-latilobate charac- 

 ter, the fastigate periphery. 1 



1. Paquieima angulata, S. Buchnan. Woodcut fig. 24 in text. 



Description. — Platy-subleptogyral, costati-gradumbilicate ; costate to striate. 

 Note. — The costate stage is well shown in the early whorls. The decline to 

 strias is rather rapid.

Fig. 24.— Paqi 



angulata. a, side view; b, whorl section; c, suture lines ; d, radial line. Haselburj. 



Locality and Stratum. — Somerset : Haselbury, from the white limestone of th< 

 " lower beds." 



Date of Existence. — Miirchisonse hemera. 



2. Paquieria floccosa, S. Buchnan. Suppl., Plate X, figs. 20 — 22. 



Description. — Platy-subleptogyral, subconcavumbilicate ; striate. 

 Note. — P. floccosa may be called an Opalinoid in point of shape and ornament, 

 but the radial curve forms an easy means of discrimination from Lioceras. 

 Distinction. — From P. angulata, smaller umbilicus. 



Locality and Stratum. — Somerset : Stoford, in a somewhat iroushot matrix. 

 Date of Existence. — Bradfordensis hemera, probably. 



1 Fastigation of the periphery is a feature varying with degree of development ; but it seems 

 doubtful if the fully costate species of this genus would have possessed such a tabulate periphery as 

 that of Kiliania laciniosa.
