 large numbers in front of their hive ami that a young queen from the same mother

 hereditary. It was gotten rid of by introducing healthy queens from healthy 

 colonies.

A new type of organism parasitic on Gregorines, M. Caullery and F. Mesnil 

 (Compi. Bind. Acad. Sei. Paris, 125 (1887), Xo. SO, pp. 787-790, Jigs. 10).— There is 

 here described under the new generic and specific name of MetchnikovelTa spionis a 

 peculiar organism probably of parasitic nature fouud in the Gregorina spionis of the 

 alimentary canal of the annalid Spio martinensis. The organisms appeai-as nucleated 

 rounded bodies. They multiply by fission and by gemination and exist in the body 

 of the gregorin in the form of chains or singly in elongated vacuoles. The bodies 

 measure about 2h /i in size and are usually arranged in 2 rows of about 16 each. In 

 the gregorine {G. anchorina) of'thecapitellid, Capitellides giardi, a similar organism 

 is found. Similar bodies have been described and figured from the gregorines of 

 other worms, but hitherto they have not been explained.
