AT THE ZOOLOGICAL STATION AT NAPLES. 475 



the British Association Table, announced his intention of going to New- 

 Britain for the purpose of studying the anatomy and embryology of 

 Nautilus pompilius, and kindly offered to assist in the erection and 

 management of the new laboratory. 



Dr. Dohrn laid great stress on the necessity of instructing native 

 fishermen for the service of the new Station in order to save European 

 naturalists as much as possible all bodily exertion connected with their 

 scientific pursuits, and to enable them to concentrate full energy on their 

 mental work. With this object in view Mr. Parkinson has sent two 

 young Papuans to Naples, and they are now being instructed by Signer 

 Salvatore Lobianco in the various and well-known arts of the Zoological 

 Station. From the latest accounts received from Naples this novel 

 experiment of transforming two Papuans into biological fishermen offers 

 every prospect of success. 



This new Colonial Station will remain under the control of the Naples 

 Station, and Dr. Dohrn hopes soon to make known such regulations and 

 conditions as may enable competent naturalists to work there profitably 

 and successfully. 



The progress of the various publications undertakeii by the Station is 

 summarised as follows : — 



1. Of the ' Fauna und Flora des Golfes von Neapel,' the monograph 

 by Dr. W. Miiller on 'Ostracoda' (404 pp., 40 plates), has been published. 

 Monographs by Dr. Biirger on ' Nemertinea ' and by Dr. Jatta on 

 ' Cephalopoda ' are in the press. 



2. Of the ' Mittheilungen aus der Zoologischen Station zu Neapel,' 

 vol. xi., parts iii. and iv., with 11 plates, have been published. 



3. Of the ' Zoologischer Jahresbericht,' the whole ' Bericht ' for 1893 

 has been published. 



4. A new and thoroughly revised German edition of the ' Guide to the 

 Aquarium ' has been published. 



The details extracted from the general report of the Zoological Station, 

 wliich have been courteously furnished by the officers, will be found at 

 the end of this report. They embrace lists (1) of the naturalists who 

 have occupied tables since the last report, and (2) of the works published 

 during 1894 by naturalists who have worked at the Zoological Station. 



The preserved specimens sent out by the station during the year 

 ending June 1895 comprised 180 consignments, amounting to about 

 14,900 fr., as against 194 consignments amounting to 17,687"70 fr. in the 

 preceding year. 



I. lieport 011 the Occupation of the Table. By Mr. M. D. Hill. 



I occupied the Table of the British Association from October 1, 1894, 

 to February 20, 189.5. 



I investigated the matui-ation and fecundation of the ova of certain 

 Echinoderms and Tunicates in order to clear up, if possible, certain 

 debated points, more especially as regards the origin and behaviour of the 

 centrosome. When I began to work, Fol's account of the ' Quadrille des 

 Centres ' had been accepted unchallenged, and so gratifying were his 

 results from a theoretical standpoint, that several text-books had re- 

 produced his figures as being true representations of what actually
