Mr. BlytlPs Commentary 
144. Meniceros bicornis (Scop.) ; Penelopides ginginianus 
(Lath.); Cabanis (Mus. Hein.). 
The last author refers this bird to the same minimum division 
as the Philippine P.panini (Bodd.) (Buceros panayensis, Scopoli), 
to which it surely is not very nearly akin, Meniceros of Gloger 
being assigned to the B. rhinoceros type, or typical Buceros , 
according to Dr. Cabanis. The adoption of Scopolds specific 
name for this species involves some inconvenience, the same 
name being also applied to the great Homrai. 
145. Toccus GINGALENSIS. 
This should be T\ griseus ( Buceros griseus, Latham ; B. cine- 
raceus, Temm.), as distinguished from the true T. gingalensis of 
Ceylon, which, together with the present species, inhabits that 
island. The two were discriminated by Mr. E. L. Layard (Ann. 
Mag. N. H. 1854, xiii. p. 260), though he describes both under 
the name gingalensis. Mr. Layard also indicates a second 
Hydrocissa, akin to H. alhirostris and H. convexa , as inhabiting 
the mountains of Ceylon. I have only seen T. cineraceus from 
Malabar and Ceylon; but Prof. Schlegel gives it from Nipal 
(Franks). 
146. Aceros nipalensis, Hodgs.; Gray and Mitchell, Ill. 
Gen. Birds, pL 99. 
The range of this species extends to the Tenasserim provinces 
(Ibis, 1864, p. 182). Dr. Jerdon refers to three species of 
Rhyticeros as inhabiting Burma and Malacca, by the names R. 
rujicollis , subruficollis, and plicatus. I know of two only, viz., 
R. plicatus (Lath., Schl.) —Rliytidoceros obscurus (Gm.), Cabanis 
—Buceros pasuran, Baffles = B. rujicollis, nobis (olim) ; and R . 
subrujicollis, nobis (adopted by Cabanis), which hardly differs 
P. caprata ; Sylvia affinis and S. curruca ; Regains himalayensis and R. 
cristatus » Dicrurus macrocercus and D. minor ; Graculus macii and G. 
javensis ; Arachnothera longirostra and A. pusilla ; Ilenicurus speciosus and 
H. frontalis; Turnix andalusica and T. dussumieri (pera) ; Nettapus albi- 
pennis and N. coromandelianus ; Laras glaucus and L. islandicus, &c. &c. 
The Loxice are robust in proportion to their size, as L. pityopsittacus, L. 
curvirostra, and L. himalayana ; so, indeed, are Laras glaucus and L. 
islandicus ; and if a species were to occur just intermediate to Totanus 
glottis and T. stagnatilis , there would be a corresponding series to that of 
Loxia in a genus of Waders.
