Calabar', a coast-district on the Gulf of Guinea, now embraced in the southern division of the British protectorate of Nigeria. Its limits are not clearly defined; but it is usually understood to extend from the Nun mouth of the Niger to the Cameroon colony. The surface is low and flat, and the climate unhealthy. Palm-oil, kernels, ebony, ivory, india-rubber, shea butter, and beni-seed are the chief articles of commerce. The Scottish Presbyterians have had a mission here since 1846, which has produced beneficial changes. Of the different tribes, the Efik, who are a negro stock, is the most important. The chief towns are Duke Town, Creek Town, and Old Town. - The Old Calabar or Cross River, believed to rise near Iko, beyond Uyanga, enters the Bight of Biafra by an estuary 9 miles broad, is mainly the estuary of the Cross River. It is navigable by steamers for 200 miles above its mouth. - The New Calabar River is a branch or mouth of the Niger. See Goldie's Calabar and its Mission (1890).
