inside the submedian nervure. The proximal half of the secon- 

 daries greyish white, rather darker towards the anal angle. 



Beneath umber-brown, the outer portion of both wings rather 

 darker, the spots on the primaries as above. 



Hab. New Ireland. 



Obs. Allied to P. codrus, from which it differs in having the 

 band of spots of the primaries interrupted, there being no spots in 

 the spaces between the first and second, and second and third median 

 branches, that between the first median branch and the submedian 

 nervure being wanting. On the other hand, there is a spot on the 

 inner margin of the primaries not usually seen in P. codrus. The 

 single specimen sent by Mr. Brown has the secondary wings slightly 

 injured, so that the prolongation of the second median branch, 

 common to all the allied species of the P. -codrus group, is broken off.

[Eeceived June 18, 1878.] 



Eighty specimens of Procellariidse are comprised in the * Chal- 

 lenger ' collection, belonging to 22 species and 13 genera. The 

 greater part of these were obtained during the visit to Kerguelen 

 Island ; others were secured at sea in the South Pacific Ocean, a few 

 near the Straits of Magellan, at Nightingale Island, and elsewhere. 

 None of the species present any difficulty as regards their nomencla- 

 ture ; but I take this opportunity of adding a few notes on this sub- 

 ject gathered during recent study of the species to which they 

 belong.
