and Lake Ngami. Another genus of tHis family, Jansenia, is 

 common to South Africa and South India. 



In the large family of Carabidae, or ground-beetles, there are 

 17 peculiar South African genera, the most important being 

 Crcpidogaster, ffytrichopus, Arsinoe, and Piezia. Three others — 

 Eunostus, Glyphodactyla, and Megalonychus — are common to 

 South Africa and Madagascar only. There is also a genus ia 

 common with Java, and one with Australia. 



Of Lucanidae, or stag-beetles, there are 3 peculiar genera ; of 

 Cetoniidse, or rose-chafers, 14 ; and of Buprestidee, 2. 



In the great family of Longicorns there are no less than 67 

 peculiar genera — an immense number when we consider that the 

 generally open character of the country, is such as is not usually 

 well suited to this group of insects. They consist of 5 peculiar 

 genera of Prionidse, 25 of Cerambycidae, and 37 of Lamiidae. 



Summary of South- African Zoology. — Summarizing these re- 

 sults, we find that South Africa possesses 18 peculiar genera of 

 Mammalia, 12 of Birds, 18 of Eeptiles, 1 of Fishes, 7 of Butter- 

 flies, and 107 of the six typical families of Coleoptera. Besides 

 this large amount of speciality it contains many other groups, 

 which extend either to West Africa, to Abyssinia, or to Mada- 

 gascar only, a number of which are no doubt to be referred as 

 originating here. We also find many cases of direct affinity with 

 the Oriental region, and especially with the Malay districts, and 

 others with Australia ; and there are also less marked indica- 

 tions of a relation to America. 



Atlantic Islands of the Ethiopian Region. St. Hehna. — The 

 position of St. Helena, about 1,000 miles west of Africa and 16° 

 south of the equator, renders it difficult to place it in either of 

 the sub-regions ; and its scanty fauna has a general rather than 

 any special resemblance to that of Africa. The entire destruc- 

 tion of its luxuriant native forests by the introduction of goats 

 which killed all the young trees (a destruction which was nearly 

 completed two centuries ago) must have led to the extermination 

 of most of the indigenous birds and insects. At present there is 

 no land bird that is believed to be really indigenous, and but one
