The results here communicated were obtained in August 1889, 

 during a long zoological excursion, which was unfortunately much 

 interfered with by unfavourable weather. The examination of the 

 three basins referred to, which are so different in every respect, will 

 be continued for several years. At the same time the investigations 

 will be extended to some other lakes of the Rhsetic Alps, especially 

 to the Liinersee, on the Seesaplaner. In this way it may be pos- 

 sible to obtain a complete picture of the Lake-fauna of a definite, 

 narrowly bounded Alpine region, and at the same time to approach 

 more closely to certain biological questions. The faunistic and 

 biological results of 1 889 are described in detail in a report which 

 appears in the ' Yerhandlungen der Naturforschenden Gesellschaft 

 in Basel.' 



Protozoa and Rotatoria were this time not particularly collected ; 

 but these groups will be studied in future years. The lists of the 

 other groups must also be greatly enriched. — Zoologischer Anzeiger,

On the Actinian Genera yEgir and Fenja. 

 By Prof. F. E. Schulze and Dr. D. C. Danielssex. 



In a ' Notice on the Actinida of the Norwegian North-Atlantic 

 Expedition,' published in the Annual Report of the Museum at 

 Bergen, Dr. Danielssen described two new genera, allied in appear- 

 ance to Peaehia and Edwardsia, but in which a complete intestine was 

 said to pass from the mouth to the posterior extremity of the bodv, 

 to open there in a functional anal pore. In a communication to the 

 ' Gesellschaft Naturforschender Freunde zu Berlin,' on the 19th 

 February, 1889, Prof. F. E. Schulze expressed some doubt as to the 

 validity of these descriptions, and suggested that the forms in 

 question might possibly have been examples of species of the family 

 Edwardsiidse which had been cut in two by the dredge. In answer 

 to this suggestion Dr. Danielssen wrote to his critic, and a portion 

 of his letter was read by the latter at the meeting of the same 

 society on the 16th April last. Dr. Danielssen says: — 



" You must not forget that I am an old zoological fisherman, who 

 has worked with the dredge for fifty years, and that during this 

 time I. have met with hundreds and hundreds of animals which 

 were mutilated in one way or another. From many years' expe- 

 rience, therefore, I can perfectly well distinguish such specimens from 

 uninjured ones. And if your supposition were correct, and I had had 

 to do with the torn-off anterior parts of animals, then, even if a mis- 

 take had been at all possible, the lower extremity of the animal 

 must show a constriction which would at once strike the experienced 

 observer. Such a constriction, in fact, does occur in certain injured
