have no doubt of its being that kind from the description ; but in the 

 figures the dark spots on the costal platės are represeuted as being 

 nearly regular, circular, broad riugs round a pale circular centre, 

 while in the specimen received from Professor Oldham the dark 

 mark on the costal plate is an irregular oblong or square mark only, 

 partly surrounding the paler centre of the shield. 



Mr, Blyth in the šame paper observes, " Emys ocellata would 

 appear to be the commonest species in the Burmese rivers, and its 

 naked parts are olive-grey, the crown blackish, with a yellowish-white 

 V-like mark over the snout, continued as a supercilium over eacli 

 eye and back upon the neck, another straight line behind the eye, 

 and both are often more or less broken into spots. 



" Carapax dusky mottled with yellowish, a great black spot sur- 

 rounded with a pale areola upon each discoidal (!) plate, dorsal ridges 

 blackish with pale border, and lovver parts wholly yellowish-white. 



" Some are brighter coloured than others, and the ocelli become 

 proportionally smaller as they inerease in size. 



" The carapax of our largest specimeu measured 9 by 6^ inches, 

 but it probably is not nearly full-grown.' '

(Annulosa, PI. XLIII.) 



The large Spiders of the New World, though generally sombre iu 

 hue, are occasionally varied in colour. The Mygale versicolor de- 

 scribed by Baron Walckenaer (Apt. i. 211), has the cephalothorax 

 covered with down-like hairs of a metallic green lustre, and some of 

 the hairs of the body have in certain aspects a violet reflection. The 

 Mygale rosea described by the šame author from the collection of 

 M. Guerin Meneville, who procured it from Chili, is deserving of its 

 specific name. The Mygale Zebrą, figured in the fourth volume of 

 the * Annales de la Soc. Eatomologique,' pi. 19, has the abdomen 

 strikingly striped. Generally speaking, however, these large Mygales, 

 whether from the 01d or the New World, are rough, plain brown, or 

 black creatures, with greyish scattered hairs. Since Walckenaer's 

 work was published in 1837, several species have been added to zoo- 

 logical science, especially in the 8vo German work of Koch. The fol- 

 lpwing species, pre-eminent for its striking beauty of colour, was 

 obtained by my friend Dr. Berthold Seemann, the distinguished na- 

 turalist who succeeded Mr. Edmonstone on board H. M. S. HeralA 

 under Capt. Kellett, R.N., C.B.
