wing-coverts and extend beyond the primaries^ not to speak of 

 other differences, are, in my opinion, sufficient to distinguish it. 

 So much for Semioptera wallacii. It must have been with 

 much regret that Mr. Wallace left Batchian without obtaining 

 the second and finer species of the form which is said to exist 

 there. Mr. Wallace's notes on the habits and living appearance 

 of this singular bird are not yet arrived. They may probably 

 guide us to some more certain conclusion as to its natural affi- 

 nities. In the mean time those who wish to become better 

 acquainted with its strange appearance, and to form their own 

 judgment on the subject, have only to pay a visit to the British 

 Museum. There, in the Bird-gallery, they will find two nicely- 

 prepared square glass cases, in which a complete series of each 

 of the Paradise-birds * obtained by Mr. Wallace is beautifully 

 mounted and arranged. 



V. — Contributions to the Ornithology of Guatemala. By Osbert 



Salvin and Philip Lutley Sclater. 



(Plate III.) 



[Mr. Osbert Salvin's first collection of birds from Guatemala 

 having arrived, I have carefully examined them, and to the 

 best of my ability determined the species. I now give a list of 

 such of them as were not mentioned in our joint article on the 

 Ornithology of Central America in last year's volume, together 

 with the whole of Salvin's notes, whether relating to these birds 

 or to others included in our first catalogue. 



I have also taken this opportunity to insert in their proper 

 places several birds well ascertained to inhabit Guatemala which 

 were not mentioned in the former list. The total addition thus 

 made to the number of the birds of Central America amounts to 

 35 species. 



It will be understood that the whole of the field-notes in this 

 article are from Salvin's pen, while I am responsible for the 



* The Great Paradise-bird {Paradisea apoda) from the Arvl Islands ; the 

 Lesser (P. papuana) from Havre Dorey, New Guinea; and the King 

 {Cicirinurii!) regiiis) irom the Aru Ishvnds.
