18G2.] MR. J. H. GURNBY ON ACIUILA DESMURSII. 14;") 



It is not easy to point out the distinction of these species in words; 

 but there cannot be a doubt about them when they are compared 

 together. 



I may here observe that Delphinus eutropia (Gray, Proc. Zool. 

 Soc. 1849, 1 ; Zool. Erebus & Terror, t. 34 ined.), which, in the 

 ' Catalogue of Cetacea ' in the British Museum, I have placed in the 

 first section of Tursia, with D. tursio and the species above named, 

 should be formed into a section of itself, characterized by having a 

 very broad muzzle shelving on the sides, and the skull shelving down 

 over the orbits, and thirty-four or thirty-five slender teeth on each 

 side of each jaw. This sectiou may be called Eutropia. 



3. Notice of a Wingless Bird, or Moho, and a Raven found 

 IN THE Island of Haavaii by Mr. W. II. Pease. By Dr. 

 J. E. Gray, F.R.S., etc. 



In a note lately received from Mr. W. H. Pease, dated Iloaohilu, 

 Nov. 20, 1861, he observes, "I noticed in a late number of the 



* Annals of Natural History ' a description of a species of bird living 

 in our islands (which was figured many years since in Dixon's 



* Voyage'), by Mr. Gould ; he refers it to the genus ' Moho.' 



" Please inform him that there is a ivingless bird of small size 

 living in the island of Hawaii, which the natives call ' Moho,' which 

 is now nearly extinct, having been killed off by the wild cats and 

 dogs within late years ; I have seen but a single specimen. There 

 is also living there a species of Raven." 



4. Some Remarks on Aquila desmursii (J. Verreaux). 

 By J. H. Gurney, M.P., F.Z.S.* 



M. Jules Verreaux, who first recognized this Eagle as a distinct 

 species, communicated his description of it to Dr. Hartlaub, by whom 

 the species was made known to ornithologists in his admirable work 

 on the Ornithology of AVest Africa. • 



My present object is to put on record some information as to this 

 interesting bird, with which M. Jules Verreaux has been so good as 

 to supply me, and also to give some indications of the changes of 

 plumage to which this species appears liable, and which I have had 

 the opportunity of examining in several examples which now form 

 part of the collection of the Norwich Museum. 



It may, however, be well to premise a few general remarks with 

 reference to the geographical distribution of this Eagle, and to some 

 of the peculiarities by which it is distinguished. 



Aquila desmursii has hitherto only been found in Tropical Africa, 

 north of the Equator, — specimens having been obtained at Bissao
