NOTES ON DOUBTFUL SPECIES OF IXODES. 



Ixodes aequalis Banks, xi. 1909, p. 276 ; 1910, p. 6, PI. Ill, Fig. 23 ( $? capitulum 

 and scutum, sketchy). The author's description and figure are inadequate : the 

 essential data which we glean therefrom are as follows : 



Male : unknown. 



Female : Scutum 1 mm. I., nearly diamond shaped, antero- and postero- 

 lateral borders subequal, many uniform punctations, lateral carinae distinct. 

 Spiracle circular. Capitulum subtriangular, porose areas rather large, sub- 

 circular, the interval less than half their diameter. Legs: coxae I-IV with 

 minute spur at postero-external angle, coxa I with short internal spine ; tarsi 

 tapering abruptly. 



Host : Otospermophilus beecheyi (California ground squirrel), Berkeley, 

 California (Drs Wellman and Wherry). Banks states that aequalis differs 

 from angustus in having a shorter and differently shaped scutum, more circular 

 porose areas, shorter tarsi, etc. According to Hooker, 1909, p. 423, the type is 

 in Banks' collection, Washington, D.C. 



Ixodes brevipes (Neumann), 1899 (Eschatocephalus crassipes Joseph, 1882, p. 16, 

 renamed owing to crassipes being preoccupied) ; only £ s found on stalactites in 

 caves (Ihanska jama, Qoba dol, etc., Krain, Austria), the hosts probably being 

 bats. Insufficiently described ; said by Joseph to have shorter legs than /. 

 vespertilionis. 



Ixodes eudyptidis Maskell, 1885, pp. 19, 20, PI. VIII, Figs. 12-14. The only 

 points given in the author's bad description, and which might be utilized, may 

 be summarized as follows : Scutum hairless, glossy ; many fine, shallow puncta- 

 tions. As the author says, it is " evidently a true tick," and that is all that 

 we can say about it. It was found " in the gape of the penguin," at Dusky 

 Sound, New Zealand. See also Synonymy under I. neumanni N. and W. 

 Judging from the bad figures, it is possible that eudyptidis = I. putus. 



Ixodes granulatus Supino, 1897, p. 16, PI. Ill, Figs. l-10,and 1897, p. 250, PI. XII, 

 Figs. 5, 6. Also Neumann, 1899, p. 164 ; 1902, p. 125. Supino's description 

 and figures are insufficient. Neumann found what Supino described as a (J to 

 be either a ? or o. Neumann supplements Supino's description, and regards 

 the species as allied to 1. minor. The points which may serve for determina- 

 tion are as follows : 



Female: L. 4-5, W. 3 - 5 mm. Scutum regularly oval (lxO'75 mm.); 

 cervical grooves scarcely visible ; lateral grooves indicated by a faintly marked 

 ridge running parallel to the borders ; many fine and uniform punctations ; 

 emargination very slight. Anal grooves diverging widely behind. Capitulum 

 long, with dorsal base subtriangular, porose areas rounded, divergent. 

 Hypostome long, narrow, lanceolate, 3 [3, 10-11 sharp teeth per file; digit
