— M. E. Yung (Comptes Rendus, August 30, 1880) has studied 
the development of the eggs of Loligo vulgaris and Sepia offict- 
nalis exposed to light of different colors. The development is 
hastened by violet and blue light; retarded by green and red. 
Yellow light behaves like white light. Larvz of Czona intestinalis 
also grew most rapidly in the violet light. Development under 
the red and green lights, though retarded, was effected in per- 
fection. 
— Besides issuing the beginning of what will be a most valu- 
able series of monographs on the Mediterranean fauna studied at 
Dr. Dohrn’s Zodlogical Station, a provisional priced catalogue of 
the microscopical preparations issued by the Station at Naples, 
has been published. It includes four different preparations of 
Protozoa, 33 of Covlenitepata. 49 of Echinodermata, 33 of Vermes, 
57 of Arthropoda, 54 of Mollusca, and 193 of Vertebrata. These 
will be as valuable as any ever sold. The price is from one to
