1872.] REV. J. E. SEMPER ON THE BIRDS OF ST. LUCIA. 647 



The following muscles were dissected, and found to agree precisely 

 with the corresponding ones in a Rook. 



Pectoralis major. Sartorius. 



Pectoralis minor. Semimembranosus. 



Coraco-brachialis longus. Semitendinosus. 



Coraco-brachialis brevis. Adductor magnus. 



Tensor patagii longus. Biceps. 



Tensor patagii brevis. Femoro-caudal. 



In conclusion, it may be stated that the anatomy of Heteralocha 

 shows clearly that it is truly Passerine, and not related to Upupa, 

 as was previously supposed by most authors*. When examined 

 more in detail, its relation to the Sturnidce is found to be very inti- 

 mate, and its structure is clearly not closely allied to that of the 

 Corvidce. In its relation to Sturnus it seems to present an exag- 

 geration of the peculiarities of that bird, which would place it at the 

 head of the family. 



3. Observations on the Birds of St. Lucia. By the Rev. 

 J. E. Semper, Colonial Chaplain. With Notes by 

 P. L. Sclater. 



[Eeceived April 20, 1872.] 



Mr. Semper having kindly sent to me, through our Corresponding 

 Member, Mr. G. W. Des Vceux, a second collection of birds from 

 St. Lucia, together with a series of notes on their habits, I have 

 great pleasure in offering to the Society a second communication on 

 this subject, supplementary to that already published in our 

 ' Proceedings 'f. 



I will first give Mr. Semper' s notes on the species enumerated in 

 my former list, and then state the additional species contained in the 

 present collection, with Mr. Semper' s notes on them. 



a. Species contained informer list. 



1 . Margarops herminieri, £.s. c. p. 268. (Molvie, or Mauvie.) 



This bird is counted as one of our game birds, and is killed in 

 large numbers from August to January yearly. About October to 

 December these birds are found in large numbers in flocks feeding 

 on the berries of certain trees ; but for the remainder of the year they 

 are dispersed in pairs, and become very poor. They breed about 

 April or May, the female building a nest of dried leaves, twigs &c. 

 on a bush or low tree, laying two eggs of a blue-green. They take 

 very little shot to kill them. 



* Mr. G-. E. Gray has placed Heteralocha in the Sturnidce in his ' Hand-list 

 of Birds.'
