VIII. — Report on a Journey for the Investigation of the 

 Torpedinei extant in the Museums of England and Holland. 



By Prof. Gustav Fritsch*. 



I take the liberty of laying before the Royal Academy of 

 Sciences the following report upon the investigations carried 

 on by me during the month of August of the present year in 

 England and Holland ~\. 



As there could be no doubt that the collections of the British 

 Museum in London would offer the greatest chance of fur- 

 thering my undertaking, I travelled direct to London on 

 Saturday, August 5, and on the following Monday I had 

 already in my hands the desired material, as Dr. Giinther had 

 had it got ready for me, in kind compliance with my wishes 

 expressed in writing. 



Among the Torpedinei there was the typical specimen of 

 Torpedo hebetans 7 Lowe, the characters of which made 

 me think it probable that it was allied to T. occidentalism 

 Storer, as well as to T. californica, and thus led to a convic-

t Note by Prof. E. Du Bois-Raymond. — Prof. Fritsch' s journey had for 

 its object to test, upon more species of Torpedinei than Prof. Peters could 

 place at his disposal in the museum here, the correctness of the conclu- 

 sion that I had deduced from what I call the Delle Chiaje-Babuchinic 

 proposition, namely that every good species of Torpedinei possesses as a 

 diagnostic character a certain average number of columns. See my

 am Mittelmeer angestellten neuen Untersuchungen an electrischen 

 Fischen/' Sitzungsb. Akad. Wiss. Berl. 1882, pp. 487 et seqq.
