November 2 Oth 1S79. — Mr. J. Christy exhibited two skulls of 

 Australian natives send by Dr. Bancroft to show an occipital thickening 

 supposed to be induced by the blows of Knobkerries ? Mr. Alfred H ad don 

 read a paper »On the Extinct Land Tortoises of Mauritius and Rodriguez« ; 

 his Communication being founded on an extensive series of remains obtained 

 by Mr. Edw. Newton and deposited in the Cambridge Univ. Museum. 



The author states that an examination of these bones corroborates the 

 two Mauritian species Testudo triserrata and T. inepta described by Dr. A. 

 Günther, but it adds no fresh example to that apparently unsatisfactory 

 species T. leptocnemis. Moreover though possessing a large series of remains 

 from the Island of Rodriguez Mr. Haddon like Dr. Günther cannot distin- 

 guish more than one species the T. Vosmaeri. As examples of the inherent 

 tendency to Variation in these animals attention is drawn to the ankylosis of 

 the coracoid with the rest of the shouldergirdle in one specimen of T. inepta 

 (a circumstance which is unique: also to peculiarities in the coracoid of T. 

 triserrata. The free coracoid of T. inepta is now for the first time recorded. 

 The coracoid of T. Vosmaeri is shown to be exceedingly irregular in its anky- 

 losis with the rest of the shouldergirdle. — There followed a paper by Mr. 

 Edw. J. Miers entitled »On a small Collection of Crustacea made by Edw. 

 Whymper, chiefly in the N. Greenland Seas ; with an appendix on additional 

 species collected by the late British arctic Expeditions«. Great novelties in 

 Crustacea could not be expected from this region of late equally explored by 

 Scandinavian and English naturalists, but the material nevertheless gives an 

 earnest of richness of fauna. The dredging was chiefly confined to the neigh- 

 bourhood of Hare Island north of Disco, in about 30 fathoms of water and 

 here animal life abounded. Some 29 species are mentioned and notes thereon 

 given. Of Crangon [Cheraphilus] boreas the author says that Mr. Kingsby 

 holds that the genus Cheraphilus as defined by Kinahan cannot be maintained. 

 Mr. Miers retains it as a sectional division of Crangon and as applied to 

 those species of large size with median and lateral series of spines on the 

 céphalothorax and with postabdominal segments all keeled ; thus in contra- 

 distinction to the smaller, less robust species (e.g. C. vulgaris, franciscorum) 

 in which the parts in question are smooth. A probable new species of Idotea 

 is described, the Cetacean parasites Cyamus nodosus and C. monodontis from 

 the Narwhal referred to, and corrections made respecting Brachinecta arctica.
