342 THE FOSSIL ECHINOIDEA 



Genus MOIRA, A. Agassiz, 1872. 

 1. MoiEA, sp. ■? 



A single small example in the Gaj collection probably belongs to this genus. It 

 is, however, so badly preserved, and with nearly the whole of the abactinal surface 

 obscured by matrix, that accurate determination is impossible ; we therefore refer it to 

 the genus with doubt, and place its occurrence on record in the hope that future 

 discoveries will furnish more satisfactory material. We were led to consider this speci- 

 men as a species of Moira on account of the indication of the presence of a narrow 

 slit-like petal, and of the peculiar ornamentation on the neighbouring plates. The 

 actinal surface is well preserved, and its outline is very near to that of M. antiqua, 

 nobis, from the Miocene of Kachh. 



Dimensions. Length of the test 16 millim., breadth 15 millim. 



Locality. In the Gaj series of strata : Entering the hills on the road from Jangri 

 to Bula Khan's Thana. Survey-number G ^^S-- 



Genus MEOMA, Gray, 1851. 

 1. Meoma, sp. ? 



There is a fragment of part of an interradial area of a large Spatangoid in the 

 collection on which the remains of a well-defined, angular, and deeply re-entrant 

 fasciole are preserved. Amongst the general miliary ornamentation of the plates are 

 small, well-spaced, primary tubercles, both within the fasciole and on the adjacent 

 plates without, where, however, they are smaller and diminished in size as they recede 

 from the fasciole. The ornamentation recalls in a striking manner that of M. ventricosa 

 (Lam.), Liitk. Unfortunately the fragment alone is insufficient for the determination 

 either of species or genus, and we therefore merely place its occurrence on record. 



Locality. In the Gaj series of strata : Near the top of the pass, on the M61 range, 

 west of Thana Shah-beg. Survey-number G -^^, 



Genus BEEYNIA, Besor, 1847. 



Large Urchins well characterized by the presence of peripetalous, internal, and 

 subanal fascioles. There are large tubercles with deep scrobicules, limited by the 

 peripetalous fasciole ; but they are absent in the posterior ambulacrum. The internal 

 fasciole crosses the four petals, and their pores situated within its area differ from 

 those without and may disappear. 



This genus was placed by MM. d'Archiac and Haime amongst the Nummulitic 

 fauna of Sind, and their species Breynia carinata was described in their great work, 

 which has so often been quoted in this Monograph, on p. 216, and delineated on 

 their plate xv, fig. 4. 



We have noticed the same species in our description of the Miocene series of 

 Kachh (" The Tertiary Echinoidea of Kachh and Kattywar," Pal. Indica, Ser. XIV. p. 66, 

 Plate X), and also on page 228 of this Monograph. There is now no doubt about 

 the correct geological horizon of the genus in the Tertiaries of Western India for
