living specimens of the worm, and watch its habits in the 

 Aquarium. Mr. Watson came on August 24th, and the 

 following day we were fortunately able to take a steamer 

 to the ground, and amongst the tubes brought up in the 

 dredge, from over 50 fathoms, one contained a fine living 

 Panthalis, which was successfully brought on shore and 

 transferred to a small tank provided with a supply of the 

 fine mud in which the animal lives. The worm was then 

 kept under the closest observation by Mr. Watson during 

 the whole day for the next week, and his enthusiasm and 

 patient care have been rewarded by the collection of a 

 number of drawings and notes and some photographs of 

 the appearance and movements of the living animal. 

 During that time the Panthalis deserted its old tube and 

 formed a new one in the mud, fortunately using the glass 

 for part of one side, so that the process of scooping out, 

 the mud and of spinning the network of mucus threads 

 and the various movements of the animal were readily 

 enough seen — if one did not mind the inconvenience of 

 lying for hours in a cramped position on the damp con- 

 crete floor of the Aquarium-room. This satisfactorily 

 settled the Panthalis question, and established the cor- 

 rectness of our previous views as to the connection 

 between the worm and the empty tubes brought up in the 

 dredge. 



Rev. T. 8. Lea, M.A., on two visits to the Station, 

 spent some time in taking photographs of characteristic 

 specimens of the Marine Algae in situ at low tide, and in 

 making microphotographs in the laboratory. He also 

 photographed some of our collecting grounds and pools, 

 and some selected pieces of rock showing assemblages of 

 animals and plants in their natural environment. 



We have again been able to send specimens of the 

 laroe red mite Bdella basteri to Mr. Michael to aid m Ins
