"SCOTIA RISE" REGION. 275 



melanophrys, was seen daily (except on one day). They were recognised as belonging 

 to the same species as the two albatroses secured at Burdwood Bank in December 1903 

 (Thalassogeron culminatus, see Section IV., p. 215), and were logged as "Burdwood 

 Bank Albatroses." None were seen in the neighbourhood of Gough Island or 

 subsequently on the voyage to the Cape of Good Hope. It is, however, equally if 

 not more probable that these birds may have been Thalassogeron cMororhynchus. 



Diomedea c.i-nfitns appeared irregularly on this voyage. Several were met with 

 on April 3rd, when one was shot, and again on the 7th, the 10th, llth, and 18th; 

 on the 19th very many were seen (nearing Gough Island, about 43 S.), but next day 

 only some young birds are logged. On the 21st, when the Scotia was lying to off 

 Gough Island, many were Hying about her all day long. 



Priocella glacicdoides, after having been unusually numerous on March 31st, was 

 seen in decreasing numbers for the next three days (up to about 57 S. J, and not again, 

 except a single example on April 17th (44 30' S.). 



" Blue Petrels " were logged nearly every day during this part of the Scotia's voyage, 

 chiefly up to 55 S., after which none were seen for several days. From 51 to 46 S. 

 one or two were seen daily, and then they began to appear in larger numbers. Many 

 were seen about 43 S., and also in the neighbourhood of Gough Island. 



As no specimens of these " Blue Petrels " were obtained in this region, it is not 

 possible to say with certainty whether they were Halnlnvnct cserulea, or species of 

 Prion, but it may be regarded as probable that most were of the latter genus 

 (see Section VII., under Halobiena). The only "Blue Petrel" obtained at Gough 

 Island was a I'limi, P. rilttn* (Gm.) (see Section IX. of this volume, p. 280). 



A fair number of Cape Pigeons (Daption capensis) were seen up to 55 S., 

 thereafter one or two per day occasionally up to 43 S. 



Giant Petrels (Ossifraga gigantea) were seen in small numbers up to 56, after 

 which none were observed for a week. About 49 they again appeared, and a few 

 were seen almost daily up to the date of arrival at Gough Island. 



Dr Bruce tells me that the Giant Petrels observed near Gough Island were dis- 

 tinctly darker in plumage than those seen in the far south. 



A white example was seen on April 1st. 



Wilson's Petrel (Oceanites oceanicus) was seen almost daily all the way, but not in 

 large numbers."" 



O 



On the 4th April a " Storm Petrel differing from Wilson's in having a white abdomen, 

 and this white extending on to the lower surface of the secondaries, except at their 

 tips," was seen. This very probably refers to Cymodroma grall&na, specimens of 

 which were obtained further north at Gough Island. It was observed almost daily 

 thereafter till Gough Island was reached. 



* In general, it may be said that Wilson's Petrel, so far as plumage is concerned, could only have been ri 

 with Oceanodromn ZmtcorrAoa (or allied forms), or with I'mcellnriii priogteaj the latter, however, has wliii. under the 

 wings a character which was at once "spotted" in l'ijiiti"lrniii<i ynillnriii.
