immured until the eggs are hatched. During this period the male feeds her assiduousl\- with 

 insects, carrion, small reptiles and fruit. When the young are hatched, male and female tear 

 away the dry plaster of mud. and thenceforth one or other of the parents mounts guard over the 

 callow young until they are large enough to leave the nest. Hornbills are, of course, monogamous, 

 and I should think paired for hfe. 



The Black Hornbill of Western Equatorial Africa resembles certain Asiatic Hornbills in the 

 difference of coloration between male and female, the adult male being black in plumage, while the 

 female has the head, back and breast of chestnut-brown. For the most part, however. 



the coloration of the large 

 Hornbills is mainly black 

 and white, the black being 

 often glossed with tints of 

 iridescent green and blue. 

 When there is any third 

 colour in the plumage it 

 is generally the chestnut- 

 red referred to. But these 

 birds are often rendered 

 still more picturesque bj- 

 brightly-coloured spaces of 

 bare skin round the orbits 

 of the eyes, or on the 

 throat. 



Two Black Hornbills 

 of West .Africa develop 

 a wattle on the throat, 

 which is leaden-blue in 

 colour, contrasting in the 

 male with the bright-red 

 and purple-blue spaces of 

 wrinkled skin at the base 

 of the beak and round 

 the eyes. The Maned 

 Hornbill of Sumatra, here 

 illustrated, has the naked 

 spaces on the face almost 

 a cobalt blue in tint when 

 the bird is alive. In 

 other forms the cheeks are 

 lemon-\ellow.

THE KING CRAB 



BY R. L POCOCIv, F.R.S. 



The King Crab is a wonderful creature for many reasons. In the first place, he holds amongst 

 existing species in the animal kingdom a position which is almost unique for its isolation. Although 

 commonly called a crab, because he lives in the sea, breathes by means of gills and uses the basal 

 segments of his legs for chewing his food, he is not a crab at all in the sense in which that term 

 should be properly understood. Indeed, there is far less of the crab about him than there is about
