Two male specimens of this species were obtained by Mr. P. O. 

 Simons near Guayaquil, in Ecuador. The fact of so large and con- 

 spicuous a Lizard having hitherto escaped zoological collectors in 

 the vicinity of so well-explored a locality as the principal harbour 

 of Ecuador is very remarkable. 



4. On some new Species of Exotic Araneidea. By the Rev. 

 OcTAVius Pickard-Cambridge, M.A., F.R.S., C.M.Z.S., 

 &c. 



[Received April 6, 1899.] 

 (Plates XXIX. & XXX.) 



The twelve species of Araneidea described here belong to several 

 families, and are from widely separated localities, — one species 

 (each) from Bogota, Natal, and Madagascar, two from Singapoi-e, 

 and seven from Ceylon. Specimens of five of those from Ceylon 

 were sent to me many years ago by the late Mr. G. H. K. Thwaites, 

 of the Eoyal Botanic Gardens, and of two by Mr. Ernest E. Green, 

 of Dickoya, Ceylon. The Singapore spiders were sent to me by 

 Mr. H. N. Eidley, Superintendent of the Botanic Gardens. The 

 Natal spider, an exceedingly fine and remarkable species of the 

 genus Poltijs C. Koch, was kindly given to me by Dr. F. N. Dimock 

 Bi'own, together with some very characteristic coloured sketches
