lichen Sitzung den Character einer persönlichen l^emerkung 

 gehabt, an der eine Correctur vorzunehmen der Verein als 

 solcher nicht in der Lage war. Der Vorstand bedauert aller-

 war ich gezwungen, wollte ich überhaupt Genugthuung erhalten, 

 die Angelegenheit der Öffentlichkeit zu übergeben, was im Zool. Anz. 

 Bd. XXIV No. 639 geschah. 



Dies zur Illustration dessen, was Herr Br. »unter eine Unvor- 

 sichtigkeit sofort freiwillig wieder gut zu machen« versteht. 



Den rein persönlichen Theil unseres Streites und die peisönlichen 

 Anzapfungen des Herrn Br. übergehe ich bis auf eine. Auf p. 467 der 

 »Abwehr« heißt es: «Bald darauf betrug sich Herr Kn. in einem 

 unserer Praktikantenzimmer mir gegenüber derart, daß ich ihm das 

 weitere Betreten der Zimmer verbieten mußte«. Herr Br. hat mir ein 

 Betreten der Zimmer nie verboten. Ihm steht zudem ein solches Ver- 

 bot gar nicht zu, da er nur Assistent und nicht Institutsdirector ist, 

 was er allerdings gelegentlich verwechselt.

 long as or longer than the stalk of the cubitus; the Triozinae^ in which the 

 stalk of the cubitus is w anting ; and the Prionomeminae^ in which there is a 

 transverse nervure towards the apex of the wing. Of the total, nine species

July 31st, 1901. — 1) and 2) Botanical. — 3) Contributions to a 

 Knowledge of Australian Entozoa. Part I. Description of a new Species of 

 Distoìììum from the Platypus. By S. J. Johnston, B.A. — Distomum orni- 

 thorlynchi^ n. sp., is found in the stomach, duodenum, and proximal portion 

 of the small intestine of the Duckbill. Its most characteristic features are

 scription only, covered by the papers of Tenison-Woods, 1875 — 1881, and 

 continued by Petterd and Beddome to 1884; and in consequence many of 

 the species have been re-described under different names. The efforts of the
