* Tlui s])ocies is Cyliie Uenneguy, letter to author, 1893) Gohius albus. This identification was made 

 by a "specialist." Dr. Gill informs me that tho name Aphya alba should be used. 



1 Nosema Xajgeli, 1857, was founded upon .V. bombycis Nicgoli, wliicli was regarded as a Schizomycete 

 (Tagebl. 33 Versamml. doutsche Xaturf. u. Aerzte, im Bonn, 1857, p. 27). 



Ci/st developmenV — In a G. afuleaius kept under observation for 

 nearly a year there existed at first a single cyst, quite regularly spheri- 

 cal, attaining nearly the volume of a pea. Very soon small secondary 

 vesicles, at first scarcely distinct, appeared upon its surl'ace, progress- 

 ively enlarged and finally, instead of the inimary cyst shelling out as 

 a whole, it split open at the most prominent point and a great part of 

 its contents escapetl, leaving in i)lace of tlie tumor an excavation irreg- 

 ularly limited by a ridge formed by the non-empty part of the small 

 sphere. The small secondary vesicles then develox)ed rapidly and very 

 soon formed an irregular strawberry-like mass. 



'Tli61olian (Annal. de Microgr., 1890, ir, p. 204; Compt. Rend, hebdoni. Soc. Biol. 

 Pari.s, 1892, iv, p. 82) also saw cysts eiilari^e, bet'ome subcutaunous, shell out from 

 their attachments into the water, and there burst.
