 1 XO'KA, a Keous of PlanU belonging to the tribe fmcAona ;r<e and 

 the gesrai JMic, so named, it is supposed, from the Indian god 

 Iswmra. The gennj is characteriaed by having a small 4-toothod 

 calyx ; corolla 1 -petaled, funneUhaped ; tube long, with the four 

 in iU mouth ; ovary 2-celled, 1-eeoded ; style single; berry 



drupaceous, inferior, 2-eeeded. The specif* are numerous, and chiefly 

 confined to India and the Oriental Archipelago. They form shrubs 

 or small trees, with opposite leaven, and stipules arising from a broad 

 base, but acute at the apex. The flowers are in terminal corymbs, 

 and are usually red, but sometime* white, and are generally highly 

 ornamental, whence several are cultivated in our hot-houses, where 

 they require to be kept in a moist heat to thrive well. Some of the 

 species are used medicinally, but not to any extent Dr. HorsBeld 

 mentions /. coccinca as employed in Java as a stimulant, and Rbeede 

 two or three other species ; but none appear to be possessed of any 

 very active properties.

 Thrushes which have the bill shorter than usual, and embracing the 

 greatest part of the Brachypodina and nearly the whole of the 

 Crateropodina of Swainson. 



T ATUKt', the name or a genus of GrallatorUI or Wading Birds,

Bill long, conical, smooth, robuit, compressed, and pointed ; upper 

 mandible trigonal and straight, the lower thicker and turned up. 

 Head and neck more or loss bare of feathers. Anterior toes united 

 at the bate by a membrane. Size gigantic. 



The i-ecies are found in South America, Western Africa, and 

 AustralaMa. IU habiU are almost entirely the same with those of 

 the Stork*. There are three species known, distributed geographically 

 a* shore. 



M. Amrrieama may be taken a* an example. 



This bird U very large in size, white ; the head and neck (excepting 

 the occiput) without feathers, and covered with a black skin, which

 white feathers. BUI and feet black.

by Geoffrey, Desmarest, and others to the form denominated IfajxJe 

 by Illiger, Ouulitit of the French, the type of which may be con- 

 sidered to be the Simia Jacchut of Linnteus. 



M. Geoflroy treats them as a family divided into two sub-genera 

 (Hapnle and Hidas), under the name of Arctopilhtci ; but the term 

 A rctopitheciu has been applied by Gesner to another animal, probably 

 the Three-Toed Sloth, whilst the latter uses Galeopithcciu to designate 

 the Sagoin. 



The characters of Jacchus are : Upper intermediate incisors larger 

 than the lateral ones, which are isolated on each side ; lower incisors 

 elongated, narrow, and vertical, the lateral ones longest ; upper canine 

 teeth conical and of moderate size ; two lower ones very small.
