498 Zoological Society : — 



animal given by John Ellis in his work on Corallines, will be satisfied 

 that the latter was not very liberal in his praise towards his contem- 

 porary. There might have been reasons why he did not mention 

 the name of Mylius, but I cannot conceive why those of CoUinson 

 and Dunze should have been omitted. 



On two new Birds from the Rio Napo. By Philip 



LUTLEY SCLATER, M.A. 

 BUARREMON CASTANEICEPS. 



Satwate oleagineus, subtus vix dilutior : remigibus et rectricibus 

 nigricanti-fuscis : pileo castaneo, lateribus capitis cum gula 

 nigricanti-cinereis : rostri nigricanti-plumbei basi pallida ; 

 pedibus nigris. 

 Long, tota 6'5, alee 3*1, caudse 2*6. 



But one example of this Buarremon was in the collection. It 

 may be arranged next to B. rujinuchus and B. latinuchus, from 

 which, however, it is easily distinguished by its general deep olive 

 colouring. 



Grallaria nuchalis. 



Satufttte bnmnescenti-oleaginea, pileo rufescentiore, nucha et re- 



gione post-oculari dare castaneis : subtus nigricanti-schistacea : 



rostro et pedibus 7iigins. 



Long. tota7'5, alae 45, caudse 2*1, rostri a rictu 1*2 ; tarsi 2"15. 



This bird is a long-legged Grallaria in structure, though in 



plumage it rather resembles the different species of the allied genus 



Formicarius, I have never seen but this one example, now in my 



collection. 



Remarks on the Habits of a Herring Gull (Larus 

 argentatus). By A. D. Bartlett. 



In calling attention to the singular and remarkable habits of a bird 

 of this species, permit me to give an extract from the ' Garden Guide ' 

 of 1852, in order that the origin of this individual specimen may be 

 perfectly known, 



" In the beginning of June 1850, a Herring Gull {Larus argen- 

 tatus) hatched out her young ones in the enclosure (No. 1 7), which 

 is overshadowed by two weeping ash trees. The male bird had 

 assisted her so constantly in incubation, that his strength gave way, 

 and he died just as the young birds were chipping out of the shell. 

 The female then became restless, left the eggs, and was only induced 

 to resume her place for the few hours which were necessary to com- 

 plete the hatch by the keeper having arranged the dead body of her 

 mate in counterfeit presentment of the position he generally took up 

 near her when not himself upon the eggs." — Extract from ' Garden 

 Guide,' 1852 



It will, I hope, be understood that the birds so hatched in 1850 

 were the parents of the individual whose habits I now wish to record.
