Minor : ala 9.0-9.3 : pileo cinereo, dorso concolori : ala subtus fere alba, axillaribus 

 et remigibus intus pure albis : margine alari nigro, fasciam nigram interruptam 

 formante. 



(E. defilippiana is very closely allied to the following species, (E. cooki, and may yet 

 prove to be identical with it, in spite of the difference of habitat ; they both differ 

 from (E. leucoptera and (E. longirostris in having the head blue-grey like the back, 

 and in the absence of a black cap. Salvin separates (E. defilippiana on the strength 

 of its having a shorter and stouter bill. 



Dr. Giglioli and Count Salvadori, in their original descriptions, compare this 

 Fulmar with (E. gularis, but with this species it has little in common, for the latter 

 is grey below, with a white throat. 



I have examined several specimens of <E. cooki and (E. defilippiana, and find them 

 difficult to separate : the latter is perhaps lighter and more pearly-grey above, and 

 appears in the dried skins to have darker feet. The culmen varies in length from 

 1.0-1.15 inch, and the depth of the bill at the nostrils is 0.3-0.35 inch. 



The range of this species, as at present known, is confined to the western 

 coast of South America, and that of CE. cooki to New Zealand and Australia, and so 

 far neither species has been recorded from the intervening area. 



(E. defilippiana was first seen in the wake of the " Magenta " on August 5th, 1867 ; 

 it followed the ship up to August 10th, in Lat. 18° 4' S., Long. 79° 35' W., not far from 

 the Peruvian coast. It reappeared again during the cruise from Callao to Valparaiso
