of the Genus Hemignatlius, Lichtenstein. 401 



pose to designate //. hanapepe^ from the name of the district 

 in which alone I found it. 



Lastly, I have to mention that there are two other well- 

 marked species of Hemignatlius^ both found by Deppe in the 

 island of Oahu, where I, liowever, did not meet with a single 

 example of the genus, owing, no doubt, to the destruction of 

 the forests there. These, again a large and a small one, were 

 described and iigured by Lichtenstein (Abhandl. k. Akad. 

 Berlin, 1838, pp. 449-451, pi. v.) — the larger one being 

 thought by him to be the Certhia ohscura of Gmelin and 

 Latham, and therefore identical with the //. obscurus above 

 named, and the smaller announced as new under the title of 

 H. lucidus. Of this last two specimens, obtained by 

 Townsend, who was for a time collecting with Deppe — see 

 the former's ^ Narrative of a Journey across the Rocky Moun- 

 tains and a Visit to the Sandwich Islands' (Philadelphia, 

 1839, p. 269) — were sent to Audubon, and from him acquired 

 by Jardine, at the sale of whose collection tliey were bought 

 for the Museum of the University of Cambridge. One of 

 these has recently been submitted by Prof. Newton, at my 

 request, to Prof. Cabanis for comparison with the type in the 

 Berlin Museum, with the result that they are found to be 

 identical. It will therefore stand as H. lucidus^ Lichten- 

 stein ; but it is obvious that the larger species is equally 

 distinct from H. obscurus (Gmelin) and from my new H. 

 Stejnegeri. According to both figure and description it is 

 intermediate in size between them ; but, from the specimen 

 described and figured being apparently a female, the other 

 differences are not so manifest. That they would be more 

 evident in the other sex may be safely inferred ; but almost 

 on the ground of size alone I am prepared to assert that 

 Lichtenstein's example is specifically distinct from the rest, 

 and I propose to name it H. Lichiensteini^ reserving further 

 details for the work on the birds of the Sandwich Islands 

 which 1 have in contemplation. 



It thus follows that there are in all six species of llemi- 

 gnathus : — 



1. H. obscurus (Gmel.).') tj 



2. B. olivaceus (Latr.). J 



3. H. Lichiensteint, mihi.") /--w i 



4. U. lucidus, Licht. J 



5. //. Stejnegeri, mihi.! j^^^^^^-^ 



6. H. hanapepCj mihi. J 



Of which nos. 2, 4, and 6 may be regarded as belonging to 

 the subgenus lleterorhynchus.
