impress of the horny teeth of tlie suckers upon the epi<lerinis, to 

 deep eiic'uhir cuts reaching to the hh\ljber. In many cases the 

 epidermis had peeled off from within the deeply cut circles, 

 exposing the corium. The circles varied in diameter from 1 inch 

 or less to 1.4 inches according to the size of the sucker which formed 

 them. These marks wei-e noticed by Pouchet and Bcauregai'd * 

 as occurring on the head of a Sperm Whale and were attiibuted by 

 them to parasitic Cirripedes which liad become detached . But. after 

 comparing these marks with the horny rings of the suckers taken 

 from the stomachs and intestines of the two specimens, and taking 

 into account the fact that the marks only occur on the head, there 

 can be no doubt that they were made by cuttlefish during their 

 struggles with the Sperm Whales who had seized them for food. 

 The marking of the skin of Odontocetes by cuttlefish has been 

 referred to by Dr. Harnier t. 



A group of V)arnacles was found attached to the foui'th anterior 

 tooth on the right side of the lower jaw of one of these whales. 

 The cluster consisted of individuals of Conchoderma auriium, 

 to one of which was attached a small specimen of C. virgatum. 

 These were the only external parasites to be seen on the two 

 Sperm Whales. 



The guts of both specimens wei'e infested with intei'nal para- 

 sites. The determination of these is in progress. 



Several of the whales wei'e fresh enough to have permitted an 

 examination to be made of their histology and of their gut 

 Protozoa, ; but unfortunately the necessary apparatus for such 

 work was not at hand at Innishkea. This was to be regretted 

 since the gut Protozoa of the Cetacea are quite unknown and 

 very little, if anything, has been written upon the histology of 

 whales. 



VII. Miscellaneous Observations. 

 1 . Locality/ of Captures. 



When the station at Innishkea was first opened in the early 

 summer of 1908, whales were taken at a distance of ten miles from 

 the island. But during the season of 1909 the steamers had to 

 go at least sixty miles out to sea before they could find a whale. 

 It was not possible to obtain the exact latitude and longitude of 

 the captures, as these we)-e kept as trade secrets by the whalers. 

 However, it is safe to say that all the whales obtained by this 

 station during the two seasons of its existence were taken within 

 a radius of .seventy miles, north, south and Avest of Innishkea. 

 This can be explained either by their being molested or by an 

 alteration in the distribution of their food. 



During my visit one of the whaling captains discovered about 

 twenty individuals of Balcenoptera musculus occupying the head
