the coral islands of the Central Pacific. The zonal distribution of coral-haunt- 

 ing mollusca is reviewed. Of Brachiopoda Cephalopoda, Polyplacophora 

 and Pelecypoda, a hundred and two species are enumerated. Of these forty- 

 two were not known to occur in Queensland, and twenty-five are new records 

 for Australia. The most interesting novelty is a new genus of the Veneridae, 

 which conceals its shell with a coat of sand; and which it is proposed to 

 distinguish as Granicorium. Fourteen other new species are distributed in 

 the genera Glycymeris (2) , Philobrya (2), Modiolaria , Myodora , Verticordia, 

 CrassateUites, Cuna, Condylocardia (2), Cardium, Gafrariutn and Ähra. Most 

 of the shells were obtained by the dredge in seventeen to twenty fathoms 

 outside the reef. A series of lantern slides Avas shown in illustration of the

 Odoiiatd\. By R. J. Tilly ard, B.A. — In this paper eleven new species are 

 added to the list of Australian Libellulidae , bringing the total up from 50 

 to 61. All the new species were taken in the Cairns district of North Queens- 

 land during the summer of 1904-05. Of these, three only are new to science. 

 The remainder are species already known in other parts of the world, but so 

 far unobserved in Australia. Of the new species, one, represented by a single 

 female, belongs to the beautiful genus Rhyothemis. A second is a Synthcmis 

 and closely allied to several common Southern Australian forms already de- 

 scribed. A third adds as new genus [Macromia] to the Australian list. Of 

 the eight remaining species, one is common in South Europe, Africa and the 

 East Indies; four others occur in the East Indies, India and Ceylon; two in 

 New Guinea; and one, hitherto known from the male only, in Borneo. Altog- 

 ether six new genera are added to the Australian list, viz., Zyxomma, Ery- 

 themis, Macrodiplax, Agrionoptcra, Tetrathemis and Macromia. In two of the 

 new species the males have yet to be discovered. — 4] Note on the Cerebral 

 Localisation in the Bandicoot [Perameles). By H. G. Chapman, M.D., 

 B.S., Demonstrator of Physiology in the University of Sydney. [From the 

 Physiological Laboratory of the University of Sydney.] — The positions of 

 the cortical motor centres in the brains of marsupials have been described in 

 the opossum [Didclpliys virginiana) by Ziehen, and by P. Cunningham; 

 and in the native cat (Dasyunis viverrinus) by Fl ash man. The results of 

 an investigation of the motor areas observed in Perameles nasuta and P. obe- 

 sula are communicated in the present paper. The centres described have 

 been found regularly in each animal and on both sides of the brain. The 

 movements obtained by stimulation of the appropriate cortex have been — 



1) Petraction of the head with rotation of the face towards the opposite side; 



2) rotation of the opposite fore-limb with backward movement of the shoul- 

 der; 3) extension of the opposite hind-limb and contraction of the muscles of 

 the back; 4) abduction and adduction of the tail; 5) closure of the opposite 

 eyelid. All the movements obtained were crossed. Other limb-movements 

 were noted by stimulation in the vicinity of those mentioned above, but were 

 not constantly found.
