been considerably greater. The greatest diameter of its shell, 

 measured obliquely from tip to tip o£ the "rays/' is 16 mm. 

 In the published records of the species the only hosts men- 

 tioned by name are species of Glohicephala \ but, as iioted 

 above, there are in the British Museum and in the Mnseniu 

 of Znolog-y, CambridfTe, specimens taken off Shetland by 

 ]\Ir. E. C. Haldane from the tail of a finner-wiiale {Balceno- 

 ptera jyhysalus). Similarly, the specimens now recorded from 

 the South Shetlands were attached near the margin of the 

 tail-Hukes of an Antarctic tinner, which many authorities 

 regard as specifically identical with B. physalus. 



XXI. — Bemahis of the Great Anh and Ptarmignji in the 

 Channel Islands. By C. W. Andrkws, D.Sc, F.li.S. 



(Published by permission of the Trustees of tlie Biitisli Museum.) 



A SMALL collection of fragmentary bones from a cave in 

 St. Brelade's Bay, Jersey, was recently sent to me by 

 Professor R. R. Marett, F.S.A., for examination. The 

 specimens were few and vevy imj)erfect, but they included 

 two interesting additions to the fauna previously recorded 

 from the locality. The most important is the upper end of a 

 riglit humerus of the great auk (^Alca impennis, Linn.) : this 

 fragment is quite characteristic and unmistakable. The most 

 soutiierly locality from which remains of the species had 

 previously been recorded is, I believe, Co. Watert'ord, where 

 ihey were fuund in liitchen-middens, and describeil by R. G. 

 Usslior in the ' Irish Naturalist/ vol. viii., Jan. 1899, p. 1. 

 Prof. j\Iarett informs me that in a recently o|)enod recess of 

 the Cavern of Gargas (Hautes Pyrdn^i s) thcie was found 

 engraved on the wall the figure of a bird which was supposed 

 to represent the great auk. If this determination turns out 

 to be correct, it would show that the range ot tliis bird was at 

 one time far greater than has hitherto been .su|)[)osed. 



The otlier interesting specimen from St. Brelade's Bay is 

 a left tarso-metatarsus of the ptarmigan [Lagopus mulus, 

 Montin, sp.), also new to this locality. Previous collections 

 include remains of the woolly rhinoceros, reindeer, cave-beai-, 

 and other characteristic Pleistocetie animals.
