36 ANNALS OF SCOTTISH NATURAL HISTORY 



March 1906, several nymphs and half a dozen females, not much 

 distended, from collie, Crosswood, Pentland Hills; loth March, 

 two females, considerably distended, from young collie, Swanston ; 

 September 1905 and September 1906, nymphs (a few) and females, 

 in various stages of distention, common on young collies at Bavelaw. 

 The male I have not yet met with ; it should be looked for in the 

 kennels or houses in which the dogs are kept, for apparently it is 

 not its habit to seek the female on the host or to accompany her 

 thither. The fasting periods of this tick are no doubt spent in 

 chinks and other places of concealment about the homes of its 

 hosts. I expect male ticks feed little, if at all, after reaching 

 maturity. In 1849 Dr. G. Johnston of Berwick gave to the dog- 

 tick of the Eastern Borders the name Ixodes canisuga (" Proc. Berw. 

 Nat. Club," vol. ii. p. 371), a fact which has been overlooked by 

 subsequent writers ; but his description is, I daresay, scarcely pre- 

 cise enough to warrant the adoption of this name for the subspecies. 



Ixodes tenuirostris, Neum. The only example of this species I 

 have seen is a fully distended nymph, which I found crawling on 

 a Water Vole (Arvicola amphibius, var. ater} from Drumlithie, 

 Kincardineshire, 3oth October 1905. I am not aware of any 

 previous record for Scotland. In England it has been taken from 

 the Field Vole and the Bank Vole. 



Ixodes putus (Cambr.) = 7. borealis, Kram. and Neum. In the 

 "Annals" for April 1906 (p. 85) I recorded and figured this tick 

 from St. Kilda, specimens (adult females and nymphs) having been 

 handed to me by Mr. James Waterston, who collected them there 

 in the summer of 1905, from Puffins and Fulmars, and on the 

 ledges frequented by these birds. Almost simultaneously it was 

 recorded from the Hebrides by Mr. Wheler ("British Ticks," in 

 "Journ. Agric. Sci.," p. 416). Since I recorded the St. Kilda 

 specimens, the Rev. O. P. Cambridge has submitted a type of 

 his Kerguelen tick to Prof. Neumann, who informs me it is a 

 nymph, and confirms him in his former determination that the 

 southern and northern forms are of the same species. I do not 

 think it necessary to use the subgeneric name Ceratixodes, and 

 Neumann himself drops it in his letters to me. 



Ixodes sp. ? A tick which I have been unable to identify with 

 any described species, and of which I have sent specimens to Prof. 

 Neumann for his opinion, occurs on Cormorants (Phalacrocorax 

 carbo) frequenting the Firth of Forth. On the head of a dead 

 immature Cormorant got on the beach near North Berwick in 

 October last, I found the remains of several examples, and from 

 the heads of two of these birds, shot in the same locality on lyth 

 November and kindly sent to me by Mr. W. Ingles, a score of 

 living larvre, nymphs, and adult females (the largest 8 mm. in 

 length) were obtained. The back of the bird's head seems to
