R h in o l o p h u s h ip p o s id e r u s m in u t u s Montagu. Vespertilio minutus Montagu, Trans. Linn. Soc. ix, (1808) p. 162, pi. 18. figs. 7-8. Diagnosis. Forearm 36,3-39 mm. Details. English and Irish individuals of Rh. hipposiderus differ from the Central European form in being on an average (and nearly always also absolutely) smaller. The length of the forearm varies, in 30 adult specimens from England, Whales and Ireland, between 36'3 and 39 mm., the average being 37‘6. In other words: the average size of the British race is considerably below-the minimum of the typical form, and almost exactly like maximum of Rh. h. minimus. Distribution. England, Wales, Ireland §. Technical name. Till the close of the 18th century, the two Bats now called Rh. ferrum-equinum and Rh. hipposiderus were * Koch's " varieties " are scarcely determinable, his descriptions being utterly vague and based upon such characters as are subject to individual variation or dependent on age : var. typus and alpinus belong, probably, to the Central European form ; var. pallidus seems to be a mixture of this and the southern race. f A glance at the measurements in Bretscher's paper is sufficient to show that what he takes to be " eine ausgesprochene Lokalform " of Hit. euryale is an ordinary, typical Hit. hipposiderus! J I ought perhaps to mention that this example, the only typical hipposiderus I have seen from Cyprus, is a dealer's specimen; a C3'prus series collected and presented by Miss Dorothy M. A. Bate (cf. P. Z. S. 1903, ii. p. 342) are unquestionably of the Mediterranean form. § For details, cf. J. E. Kelsall, " The Distribution in Great Britain of the Lesser Horse-shoe Bat," The Zoologist, xiv. (1887) p. 89. |
