136 PEOP. ST. GEORGE MIT ART ON 



A pitcliy red species, densely clothed (even on the legs and 

 tarsi) with bright golden and ochraceous round scales ; the 

 ochraceous scales form on the thorax a patch above each anterior 

 angle and a line on each side of the middle ; on the elytra a small 

 spot on the side (about the middle), and a larger oblique sub- 

 apical patch not reaching the suture ; these ochraceous scales also 

 appear golden when viewed obliquely. The scales on the abdo- 

 men and p3^gidium are more silvery. The clypeus has the mar- 

 gins distinctly reflexed and the angles much rounded. Thorax a 

 little narrower than the elytra, one fourth broader than long, 

 distinctly narrowed in front and behind, angular at the sides, re- 

 gularly convex above. Elytra one fourth longer than broad, 

 moderately depressed above, but not flat ; the sides are subpa- 

 raliel, scarcely arcuate, the subapical callosity very little promi- 

 nent. In some lights the golden scales on the elytra present a 

 mark like an X, embracing the more ochraceous scales. 



Notes touching Eecent Researches on the Eadiolaria. 

 By St. Oeobge Mivart, Zool. Sec. Linn. Soc. 



[Eead January 17, 1877.] 



The example which has been set by our President in pub- 

 lishing* from time to time in his successive Addresses a digest 

 and rSsume of the most recent researches which have been 

 carried on respecting certain of the lowest animal groups, has led 

 me to believe that a similar course might advantageously be 

 taken with respect to the Eadiolaria. Our publications already 

 afi'ord, through Dr. AUman's recent labours, the readiest means 

 of obtaining a knowledge of the most modern investigations 

 with respect to various groups of Protozoa ; and I have myself 

 found the memoirs referred to most valuable and useful. I 

 hope that other Fellows may adopt a similar course ; so that our 

 Journal may become a complete repertory of information respect- 

 ing all the lower groups of the animal kingdom. No English 

 publication on the Eadiolaria exists to my knowledge ; and 

 although the most admirable monograph f of Professor Haeckel
