* The species is (fide Henneguy, letter to aiithor, 1893) Gobius alhus. Tbis identification was made 

 by a " specialist." Dr. Gill informs'me tbat the name Aphya alba should be u.sed. 



1 Nosema Xajgeli, 1857, was founded upon N. bombycis NiBgeli, wbicli was regarded as a Scbizomycete 

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



Cyst developments — In a G. aculcatus 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 surface, progress- 

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

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

 its contents escaped, leaving in place of thetnmor an excavation irreg- 

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

 si)here. The small secondary vesicles then developed rapidly and very 

 soon formed an irregular strawberry-like mass. 



'Th^lohan (Anna!, de Microgr., 1890, li, p. 204; Compt. Rend, hebdom. Soc. Biol. 

 Paris, 1892, iv, p. 82) also saw cysts enlarge, become subcutaneous, shell out from 

 their attachments into the water, and there burst.
