strata from which the fossils were obtained. Mr. Wood describes 

 above twenty Mollusca from the Crag, which are either new addi- 

 tions to the fauna or rectifications of others already named. 



4. Professor Owen's Monograph is devoted to a description of the 

 bones of the fore-arm and paw of the Iguanodon, and is important 

 as showing that what was considered by Dr. Mantell to have been 

 the " horn" is now known to be a spur attached to the distal end of 

 the radial bones, and which in a former Monograph Professor Owen 

 inferred, from its imsymmetrical character, to be one of a pair of 

 bones conjectured by him to be "phalangeal." The author also 

 illustrates the bones of the fore-foot not previously described, and 

 which " give evidence that the fore -paw was pentadactyle, and that 

 the terminal phalanges, at least some of the toes, were short, obtuse, 

 rough, serving for the support of horny matter in the shape of a 

 hoof rather than that of a claw." 



5. Messrs. Boyd, Dawkins, and Sanford contribute a fourth part 

 of the British Pleistocene Felidce, including the character, range, and 

 associated animals of Felis pardus, F. caffer, F. catus, and Machce- 

 rodus latidens. Of the six species of Felidce noticed in this and the 

 preceding Monograph, two have been added by these authors to the 

 catalogue of British fossil animals, — the panther, or leopard, and 

 the Felis caffer, — the latter of these having been hitherto unknown. 

 in Europe. This animal, as well as the lynx, panther, wild-cat, 

 Felis speleea, or lion, lived during the Pleistocene age. 



Machcsrodus latidens is the only aberrant member of the Felidee in 

 Pleistocene times which has become extinct. To account for the 

 absence of the Lion in prehistoric times in Europe (whereas it oc- 

 curs both in the Pleistocene and Historic periods), Mr. Dawkins 

 suggests that during the long interval which -elapsed between these 

 latter, it had retreated from Northern and Central Europe partly 

 from the competition with man, and partly from the operation of the 

 same obscure causes which banished the Spotted Hyaena and the 

 Hippopotamus to Africa. 



6. Mr. Dawkins gives, in Part V., a fair history of the Ov^bos 

 moschatus — both as to its distribution in Great Britain and the Con- 

 tinent, and adopts De Blainville's views in placing it among the 

 Ovidee instead of the Bovidse as heretofore. 



In this country it has been found at Crayford, Green-street Green, 

 Freshford near Bath, Barnwood near Gloucester, and at Salisbury. 



It has also been found in France, Germany, Siberia, and America, 

 on the Northern Continent of which it is now found living, ranging 

 over the " Barren Grounds " and the River Mackenzie through 105 

 degrees of latitude. The Musk-sheep proves to have had a greater 

 range in time than was formerly suspected, having been a contem- 

 porary of the Megarhine Rhinoceros during the Pleistocene period 

 when the Lower Brick-earths of the Valley of the Thames were 

 being deposited. 



We heartily congratulate Mr. Wiltshire on the excellent working 

 of this Society, which owes a large proportion of its success to his 

 energetic and practical action as its Honorary Secretary.
