(2) Mr A. G. Bennett, at one time naturalist to the Government of the Falkland Islands, has 

 provided another record of the occurrence of H. planifrons. He obtained photographs of a specimen 

 killed in the vicinity of the South Orkney Islands in January 191 5. 



One of the photographs, in which the carcass is floating in the water alongside the factory ship, 

 shows the surface of the skin scored by numerous irregular marks. Similar streaks have been noted 

 in other ziphoids and are presumed to be the teeth marks of other individuals of the same species. 

 In addition to these elongated scratches one or two oval marks can be seen. They are reminiscent 

 of the scars described and figured by Mackintosh and Wheeler (1929) as occurring in various members 

 of the whalebone whales. Other features which can be observed in the photograph are the pronounced 

 ' forehead ' which rises at almost a right angle from the well-defined beak ; and the right flipper which 

 is of typical ziphoid form, having a very shallowly convex lower border and slightly more convex 

 upper edge. 



A second photograph gives a ventro-lateral view of the anterior portion of the body, lying on the 

 deck of the whaling vessel. The region of the mouth and throat, as far back as the two ventral grooves 

 is of a much lighter colour than adjacent portions of the body. The ' forehead ' appears to be quite 

 darkly pigmented. The rostrum is stout and well defined and the upper and lower lips meet in a line 

 which anteriorly is horizontal but farther back swings obliquely upwards.
