and Lake Ngami. Another genus of this family, Jansenia, is 
common to South Africa and South India. 
In the large family of Carabidz, or ground-beetles, there are 
17 peculiar South African genera, the most important being 
Crepidogaster, Hytrichopus, Arsinoé, and Piezia. Three others— 
Eunostus, Glyphodactyla, and Megalonychus—are common to 
South Africa and Madagascar only. There is also a genus in 
common with Java, and one with Australia. 
Of Lucanidz, or stag-beetles, there are 3 peculiar genera; of 
Cetoniide, or rose-chafers, 14; and of Buprestide, 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 Prionide, 25 of Cerambycide, and 37 of Lamiide. 
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 Reptiles, 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. Helena.—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
