264 Mr. H. J. Ccarter on the Opaque Scarlet Spherules 



Variety A, ? . — Similar to no. 3, but with the discoidal 

 stripes of the thorax uniting before the middle and continued 

 posteriorly as one broad band to the basal spots with which 

 it unites ; the lateral stripe reduced to two very small spots. 

 The red colour of the elytra prevails ; the yellow at the apex 

 inconspicuous. Pygidium with an oblong spot in the middle. 

 Abdomen with transverse spots at the sides,

Long, 17 lin. 



Very similar to C. fulgidissima, but less brilliant, with less 

 golden tints ; relatively shorter and more strongly punctured 

 throughout, especially on the disk of the thorax. The elytra- 

 are distinctly enlarged at the middle, and are consequently 

 less gradually narrowed to the apex, which is slightly trun- 

 cate, the sutural angle slightly dentiform. The costse are 

 strongly marked.

XXXII. — On the Nature of the Oj^aque Scarlet Spherules 

 found in the Chambers and Canals of many Fossilized 

 Foraminifera. By H. J. Caeter, F.R.S. &c. 



In the number of the 'Annals' for last month (p. 172), 

 while describing two new species belonging to the Loftusiidai, 

 I had occasion to lay particular stress on the presence in 

 them, as well as in Loftusia persica^ of " opaque scarlet 

 spherules," which, although for the most part dispersed 

 through the substance of the fossil, are nevertheless fre- 

 quently to be seen in the chambers of the foraminiferal tests 

 that have been taken in by each of these species, from 

 which it may fairly be assumed that all had this origin ; 

 and these spherules I have further assumed to be representa- 

 tive of the reproductive bodies of the Foraminifera from 

 observations which led to this conclusion (p. 177). Such
