angle forwards, while its disc is excavated in a longitudinal oval 

 groove (PL LIV. fig. 11). Otherwise the palpal organs very much 

 resemble those of L. columbianus F. Cambr. The Spider from 

 Trinidad is, however, very much larger, while the patella and tibia 

 of the first pair of legs are together shorter than those of the 

 fourth pair. In columbianus they are equal. 



A single adult male was sent by Dr. Ince, from Trinidad.

4. On the Moulting of the King Penguin [Aptenodytes 

 pennanti) in the Society's Gardens. By W. E. de 



WiNTON, F.Z.S. 



[Eeceived October 28, 1898.] 



A King Penguin living in the Society's Gardens has lately gone 

 safely through the moult ; this moult has been the only one made 

 during the 16 months that this specimen has lived in the Gardens. 

 Two specimens, S &> ^ , were purchased on June 23rd, 1897. 

 The female died early in October, from tlie heat at the end of 

 the summer of last year, before getting acclimatized. 



The only opportunity of observing the moult of any member of 

 this order of birds which has been taken advantage of and the 

 facts published is that of the smaller and very widely different 

 species Splieniscus humlolrlti as recorded by the late Mr. A. D. 

 Bartlett in the P. Z. S. 1879, p. 6 ; and as that was a case of 

 moult from the plumage of the j oung bird to that of the adult, 

 and the present instance is a simple moult of the adult bird, the 

 facts are thought « orth recording. 



It is to be regretted that careful notes of the changes were not 

 made daily and more accurate dates noted ; but not being primarily 

 interested in oimithology I thought that someone else would have 

 been watching the change, and so can only very roughly describe 

 some of the most striking features of the moult.
