350 Mr. Blyth's Commentary 



144. Meniceros bicornis (Scop.) ; Penelopides ginginianus 

 (Lath.); Cabanis (Mus. Hein.). 



The last author refers this bh'd 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 Scopoli's specific 

 name for this species involves some inconvenience, the same 

 name being also applied to the great Homrai. 



145. TOCCUS GINGALENSIS. 



Ttis 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 

 (Fi'anks) . 



146. AcERos NiPALENSis, Hodgs. ; Gray and Mitchell, 111. 

 Gen. Birds, pi 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. 

 ruficollis, suhruficollis, and plicatus. I know of two only, viz., 

 R. plicatus (Lath., Schl.) = Rhi/tidoceros obscurus (Gm.), Cabanis 

 ^= Buceros pasuran, Baffles = 5. rujicollis, nobis {olim) ; and R. 

 suhruficollis, nobis (adopted by Cabanis), which hardly differs 



P. caprata ; Sylvia qffinis and S. cm-ruca ; Regulus himalayeiisis and H. 

 cristatus; Dicrtinis viacrocercus and D. minor; Graculus macii and G. 

 javensis ; Arachnothera lonyirostra and A. pimlla ; Henicuriis speciostis and 

 H. frontalis ; Turnix andalusica and T. dussmnieri (vera) ; JVettapus alhi- 

 pennis and N. coromandeliatms ; Larus glaucus and L. islandicus, &c. Sec. 

 The Loxice are robust in proportion to their size, as L. j)ityopsittactis, L. 

 curvirostra, and L. himalayana; so, indeed, are Larus ylaucus and L. 

 islandicus; and if a species were to occur just intermediate to Tot anus 

 (jlottis and T. staynatilis, thfere would be a corresponding series to that of 

 Loxia in a genus of Waders.
