NOTE ON TRANSCAUCASIAN FORMS OF 

 H. CINNABARINA. 



In the collection of ticks left with us for determination by Dr 

 Dschunkowsky of Siirnabad, we have found a number of specimens 

 of typical H. dnnabarina var. jmnctata intermixed with forms in 

 which the characteristic long spine on the fourth coxa of the cT is 

 either reduced in size or practically absent ; these specimens conform 

 to the type in other respects. Details regarding these specimens 

 will be found in the section relating to Asia under Geographical 

 Distribution (see p. o87). One lot especially (N. 780) contained 

 transition forms : a typical long-spined </*> 1 </ with a moderate 

 spine and 5 (/s with very short spines. We have received precisely 

 similar specimens from Smyrna (N. 25.54) 1 cT 2 $ taken from sheep, 

 but the cf had the usual long spine. 



Haemaphysalis crassa Warburton, 1908. While examining the 

 ticks in the British Museum in 1907, we found, in a tube labelled 

 " No. 2-54. H. papiiana" two gorged $ s which certainly did not 

 belong to this species and which we were then unable to identify. 

 One of us described them under the name of H. crassa (see Fig. 323), 

 in allusion to their unusually rugged appearance. They were taken 

 from cuttle at Surnabad and presented to the Museum by Dr 

 Dschunkowsky to whom we have since been indebted for the oppor- 

 tunity of studying all the material he collected in Transcaucasia. 

 After due consideration we believe that H. crassa represent only 

 aberrant forms of H. cinnaharina var. punctata. 



Geographical Distribution and Hosts. 



Although widely distributed, H. cinnaharnna var. punctata is a 

 relatively uncommon tick. It occurs in Europe, Asia, and Africa as 

 the following records show. [Records by other authors are enclosed 

 in square brackets.] 



EUROPE: England: We have received all our adult specimens 

 from sheep in Kent, as follows: (N. 2151) Lydd, 13. ill. 1905, S. T. 

 Sellens coll.; (N. 899 and 1564), ditto, iii. and iv. 1905; (N. 2780) 

 ditto, 25. V. 1914 ; (N. 2152) Littlebourne, 5. iv. 1905 ; (N. 1565) 

 Heme, iv. 1905 ; (N. 1207) Ashford, v. 1906, Mr Spanton coll. ; all 

 of these specimens were collected at the instance of Mr W. F. Cooper. 

 Prof. R. T. Hewlett has presented (N. 304) specimens from sheep.
