into the heart. In young specimens of Panlosa I have seen globules 

 leave the two abdominal currents, some near the spinnerets and 

 the others towards the middle of the ventral face, pass round the 

 sides of the abdomen and fall directly into the pericardium. Finally, 

 in some young individuals of Pardosa and Heliophanns globules, 

 instead of penetrating into the lung, skirted its external border, and 

 then, circulating beneath the integument, passed directly into the 

 pericardium. 



In conclusion : the vascular system, which is very little ramified 

 in newly hatched spiders, becomes complicated later on ; the venous 

 blood circulates in a very extensive series of lacunas. The whole of 

 the venous blood of the cepbalothorax is arterialized before reaching 

 the heart : a portion of that of the abdomen returns directly to the 

 pericardium, and from thence to the heart, without passing through 

 the lungs. — Compies Renclns, t. cxiv. no. 18 (May 2, 1892),

A Contribution to the Knowledge of the Anatomical Structure of the 

 Sexual Organs in the Galeodidcp. By A. Biktjla, of the Zooto- 

 mical Institute of the University of St. Petersburg. (Provisional 

 Communication.) 



The chief results of my investigations into the anatomico-histo- 

 logical structure of the genital organs in the Galeodidse are the 

 following. 



My studies were conducted upon : — 



a. Galeodes araneoides, Pall. (J & $ ) ; 

 h. Galeodes ater, Bir. ( $ ). 



The male geuital organs are constructed as follows : — 



1. The external genital aperture is represented by a longitudinal 

 slit in the protuberance of the posterior margin of the first abdo- 

 minal segment ; 



2. Aciniform (so-called accessory) glands, with a chitinized 

 intima, open into the uterus masculinus, which is clothed with 

 chitin ; 



3. Each of the seminal ducts (vasa deferentia) divides in the third 

 abdominal segment into two rami, which, suddenly narrowing, pass 

 into the filiform testes ; 



4. In the walls of each vas deferens, at their opening into the 

 uterus masculinus, lie aciniform accessory glands, with columnar 

 epithelium, but without an intima; 



5. At the period of the maturity of the sexual products the end 

 of each ramus of the vasa deferentia, which is histologically indis- 

 tingixishable, swells up into a vesicle and functions as a vesicula 

 seminalis ; 



(t. Tlic testes consist of four thin and very long loilod tubes, which,
