obtained on the Zambesi on the 26th February, 1904, by 

 Dr. S tocher, and presented by him to- the South African 

 Museum. Dr. Sclater stated that there could be no doubt 

 that it was a fully adult male of this rather scarce species, 

 which ha*! been originally described from an Abyssinian 

 specimen, but was now known to extend all down the eastern 

 side of Africa into Rhodesia. In the series now in the 

 British Museum there were specimens from Abyssinia, 

 Sonialiland [Hawker), British East Africa {Johnston) , Nyasa- 

 land [Manning), and Mashonaland [Darling). 



Mr. W. L. S. Loat was introduced by Dr. Sclater to the 

 Members of the Club, and exhibited a series of Blue-throated 

 Robins, mostly belonging to the forms known as Erithacus 

 cceruleculus (Pall.) and E. cyaneculus (Wolf). With the 

 exception of one specimen procured to the south of Wady 

 Haifa, all were collected in the delta of the Nile, at Wady 

 Natron, and on a patch of cultivated ground close to the 

 north side of Lake Menzaleh, a few miles from Damietta. 

 E. cyaneculus was only represented by one fully adult male 

 specimen, and was apparently extremely rare ; all the re- 

 maining specimens were probably referable to E. cceruleculus, 

 which was represented in all stages of plumage. 



Mr. W. B. Ogilvie-Grant exhibited pairs of two species 

 of Woodpecker, viz. : — Chrysocolaptes gutticristatus (Tickell) 

 and Tig a shorei (Vigors), collected by Captain A. Mears at 

 Mingin, Upper Chindwin. 



He pointed out that both in their colours and markings 

 these species resembled one another so closely that, at the 

 first glance, one might easily mistake one for the other. A 

 more careful examination, however, revealed the fact that 

 the species, though superficially so alike, were structurally 

 very distinct and belonged to different genera, the former 

 possessing four toes, the latter only three. 



Mr. Grant thought that these birds, belonging to widely 

 different sections of the same family, afforded a remarkable 

 instance of unintentional mimicry, caused, no doubt, by the 

 influence of the same local surroundings. He was not aware
