Russian Ixodoidea 
Remarks upon a paper by Yakimoff, Winogradoff and 
Kohl-Yakimoff, in this Bulletin, vol. V, pp. 3 ç-pi. 
By George H.-F. NUTTALL, F. R. S., Cambridge. 
In the short paper referred to there are several errors which 
require correction : 
i) Argas per siens (O ken, 1S19) is wrongly refer red to as hav- 
ing been named by Fischer de Waldheim. The paper by the 
latter author did not appear rrntil 1823. We (1) gave the syno- 
nymy of this species.in Ticks, Part I. (1908), p. 8. It is ,a common 
error to refer the species to Fischer. 
The authors take exception to the statement in Ticks I, p. 20, 
that Neumann had reported the species from Russia, stating that 
lie had expressed himself doubtfully on the point. Neumann (1901, 
p. 253) did State clearly that A. persicus was found. at Ssamjam, 
Russia. Since the appearance of Ticks I. he (1911, p. 121) has, 
however, expressed himself doubtfully on this matter by insert- 
ing (?) after the word Russia. We can searcely be reproached 
with inaccu raey in view of the respective dates on which Neu- 
mann’s and our publications appeared. Neumann (1901, p. 253) 
States that A. persicus was collected at Ssamjam, Russia, by 
A. Spoof (2), and that the specimen was in Oudemans’ collec¬ 
tion. Professer Oudemans, to whom we wrote on the subject after 
Ticks I. appeared, informed us that the supposed Argas persi¬ 
cus is in realitv Argas reflexus, and that it was collected by 
Dr. A. R. Spoof in Ssamjani, near the mouth of the Volga and 
Caspian Sea. 
The authors refer to Argas persicus miniatus as a variety oc- 
curring in America. Neumann (1905, p. 240) could find no cons¬ 
tant différence between A. miniatus C.-L. Koch, 1844, and A. 
persicus, and largelv because of its geographical distribution re- 
(1) Nuttall and Warburton Ticks I (1908), II (1911 ). The References will 
be found in the Bibliography. (Published by the University Press, Cam¬ 
bridge). 
(2) Wrongly spelt « Spoot » by the authors in quoting from Ticks I.
