178 Mr. H. J. Carter on 



between the chambers being filled with bright ochraceous 

 yellow matter, and the opaque scarlet spherules in the cham- 

 bers of the central plane — especially brilliant in Orhitoides 

 dispansaj but less so in Nummulites Ramondiy from not being 

 so highly coloured (that is, rather brownish), and being imbed- 

 ded in the clear calcspar filling one of the central plane of 

 chambers, where they are also a little translucent and separated 

 — look like the " roe of a herring ; " so that, but for these 

 specimens, I should never have realized the nature of these 

 bodies either in StoliczMella Theohaldi or Loftusia persica. 

 I have already alluded to the fragments of marginal cord and 

 intercameral septa scattered throughout the body-substance of 

 both these specimens, in which, from the absence of stride on 

 the calcspar in the microscopic slice of Loftusia persica, they 

 are much more evident than in the Karakoram specimen, 

 where, on the other hand^ all the grains of this mineral are 

 striated (that is, present the lines of cleavage), and thus by 

 intercrossing more or less obscure their outlines. 



At this period I received from my kind friend Dr. J. 

 Millar, F.L.S. &c., several specimens of Parkeria that had 

 been obtained from the Cambridge Greensand, both massive 

 and in their microscopic sections, among which was one 

 (noticed by Dr. Millar as different from the rest) which proved 

 on examination to be a species of Loftusia, but so unlike 

 Loftusia persica and Stoliczkiella Theohaldi that it must form 

 the type of a tJii7^d genus of the family Loftusiidte, for which 

 1 would propose the name of '''' Millarella^'' and for the speci- 

 men that of Millarella cantabrigiensis, after the friend who 

 gave it to me and the locality from which it was obtained *. 



Millarella cantahrigiensis, gen. etsp.n. (PI. XIII. figs. 6-8.) 



General form subspherical, with a small, irregular cup-like, 

 shallow excavation about 4-8ths of an inch in diameter at one 

 end (? accidental) f. Consistence hard and earth-like, not crys- 

 talline. Surface very rough and irregular, unevenly granu- 

 liferous throughout. Granulations of three sizes, viz. small, 

 minute, and microscopic, the former of a brown colour charged 



* T was writing this paper, viz. about the 8tli January, 1888, and on 

 the 19th, after eleven days' illness of bronchitis, Dr. Millar died. Then 

 lost Natural History one of her ablest advocates and I one of my best 

 and dearest friends ! 



t This now appears to have been the place where the organism was 

 originally attached to some submarine object (see concluding part of 

 footnote, p. 181).
