except that the skin is unusually thickly beset with the small 

 round glands, which are very distinct. Mouth-parts and 

 antennas ordinary. Caudal tubercles represented by brown 

 chitinous bristly patches. 



Larva (according to King) yellow, of a different colour 

 from that of K. galliformis.

Easily known from the common K. galliformis, Riley, to 

 which it is most allied, by the smaller size, more regularly 

 globose form, lively colour, and the very distinct and nume- 

 rous dark points. I received two specimens years ago from 

 Prof. Gillette, and at that time regarded them as a fern of 

 galliformis ; but Mr. King now draws my attention to the 

 fact that the species is distinct, and on making a detailed 

 study of it I am surprised that I ever thought otherwise.

XXXVIII. — On Ostracoda from the " Cambridge Greensand." 

 By Frederick Chapman, A.L.S., F. 11. M.S. 



The Ostracoda from the Cambridge Greensand in the neigh- 

 bourhood of Cambridge were remarked upon, and a list of 

 seven species was given, by Prof. Sollas in 1872 *. These, 

 with some useful corrections in nomenclature, were repeated 

 by Messrs. Jones and Hinde in their " Supplement to the 

 Monograph on the Cretaceous Eutomostraca of England and 

 Ireland " f. 



In this latter work, at pp. 59 and 60, Messrs. Jones and 

 Hinde also insert a list of thirteen species of Ostracoda from 

 the Cambridge Greensand, collected by the late Mr. G. R. 

 Vine in 1889. This list, which had been compiled for him 

 by Messrs. Jones and iSherborn, was published earlier in a 

 paper by Vine \. 



Latterly the author of the present paper has had thd oppor- 

 tunity of examining some material from the Cambridge 

 Greensand collected at Swaffham, and which was kindly 

 furnished him, through the courtesy of Mr. A. J. Jukes- 

 Browne, by Mr. H. Woods, of Cambridge. The results have
