The MoUusca are very abundant, and from 15 to 30 per cent, of 

 the species are identical with those of the present age. 



The Pisces are numerously represented, and, in addition to the 

 remains of numbers of species belonging to the Telostei, teeth of 

 several extinct species of Sharks of gigantic size have been discovered. 



The Amphibia include Salamandrida and JRanidcd; and the Reptilia 

 are represented by Crocodilia and Chelonia. 



TheAves, although all of extinct species, belong, without exception, 

 so far as is known, to existing Groups. 



The Mamtnalia are abundant, and include representatives of all 

 the existing Orders except Bimana (man). 



The Plant* life of this Period was of a very varied and luxuriant 

 character, but as the majority of the species belong to existing groupsf 

 they call for no special notice. The geographical distribution of the 

 species was, however, widely different from that of the present day, 

 and the Miocene flora of Europe includes a remarkable intermixture 

 of forms, many of which are now characteristic of tropical or sub- 

 tropical countries.

Capture of a Dufourea in Hants, a genus of Hymenoptera new to Britain. — 

 On the 12th of August last, while sweeping among wild camomile flowers and low 

 herbage along the undercliff near Chewton, Hants, I took a species of Dufourea, one 

 of the short-tongued bees, which Thomson, in his " Hymenoptera ScandinaTise," has 

 united with Rhophites, a genus of long-tongued bees {lingua pectus fere superante, 

 I. c, ii, 117) ; which fundamental differences in structure and habit, together with 

 others in the alary venation, he reduces to sectional characters. 



Lepeletier de St. Fargeau, in defining the genus Jjufourea, from Latreille's col- 

 lection (having never taken it himself), mentions that the females have a large head 

 like Panurgus, while the males, in general form, closely resemble those of Halictus. 



My specimen is a male, coinciding with St. Fargeau's description of D. minuta, 

 excepting in having the legs and antennae black throughout ; but, as depending upon 

 a single example, and in the absence of a female, I can only regard this as a variety 

 of the aforesaid, with which it corresponds in size, namely, about 4| lines. 



A foreign specimen of the female of D. minuta is in the British Museum ; and 

 a male (from Switzerland) apparently identical with mine, but uiider a wrong name 

 {Andrena lucens, ^ , Imhoff), has recently been transferred to the Museum collection 

 from that of the late P. Smith. 



Rhophites was first added to the British Fauna in 1877, the R. quinquespinosus 

 having been taken in that year by the Kev. E. N. Bloomfield at Guestling, near 

 Hastings (Proc. Ent. Soc, 1877, p. 32) ; and again in August, 1878 (Ent. Mo. Mag., 

 XV, p. 113). 



The genus Dufourea is new to Britain. — S. S. Saundees, Gatestone, Upper 

 Norwood : December, 1879.
