fascia. The femora, as well as the tibia; and tarsi, are rufous. 

 Beneath, the colour of the abdomen is shining black, with 

 yellow belts across the segments.

 On flowers in June. Found also in N. China.

Not uncommon in Japan ; also N. China. 



The conical tubercle of the mesosternum being present in 

 other species of the genus, there is no reason for retaining 

 Sternoplistes of Guerin. As to the form of the tliorax, short 

 and transverse, Purpuricenus including a great diversity of 

 form of this organ (e.g. P. Angasii^ White), this character is 

 quite insufficient as a generic difference.

Mr. Lewis did not meet with this species (or variety ?) , 

 which is distinguished from P. Temminckii (according to the 

 description) only by the suture and a point on the posterior disk 

 of the elytra being black. I have a specimen of P. Temminckii 

 possessing the black discoidal point, but none in which the 

 suture is black.

XXVI. — On the Primary Divisions of the Brachiopods. 

 By Theodore Gill, M.A., M.D., Ph.D. 



The article in the July number of the ' Annals & Magazine 

 of Natural History ' (xii. pp. 1-17), by Prof. King, on Lingula, 

 exhibits tlie insight into relations and skill in discussion cha- 

 racteristic of its author ; and his views respecting the classifica- 

 tion of the Palliobranchs or Brachiopods into two primary 

 groups will probably be accepted. Indeed they had abeady 

 been quite generally adopted ; but as Prof. King had over- 

 looked the fact, it is presumed that it is not as well known as 

 might have been supposed ; and the object of this note is to 

 direct attention to the antici])ation by others of Prof. King's 

 views. The essential distinctions of Prof. King's groups arc 

 that in one ( Tretentcrata) the intestine has an anal aperture,
