those better entitled to it. It is freely admitted that this charge may 

 even be justly made ; but the limits assigned to the record have been 

 exceeded, and the recorder has studied the needs of the many rather 

 than of the few. The summary is intended, not for the advanced scientific 

 student, but for those who entertain a general interest in zoology or 

 some of the better-known classes. 



The compilation of this record has been greatly facilitated by the 

 •' Zoologischer Anzeiger" of Professor Carus and the very useful synop- 

 ses published in the Journal of the Eoy al Microscox)ical Society of London. 

 The value of both of the records thus referred to is, however, very greatly 

 reduced by the absence of an index to names of authors cited in the 

 first, and to the neglect to give a reference to the exact title and place of 

 publication of the original j)aper in connection with the abstract in the 

 latter case. The consequence is that very much valuable time must be 

 lost to confirm and find references. 



ANAL RESPIRATION IN ANIMALS. 



Mr. M. M. Hartog, in connection with observations on the anal respi- 

 ration of Cyclops^ as well as Canthocamptus of the Harpacticidse and 

 Diaptonius of the Calanidse, has enumerated the forms of Invertebrates 

 in which anal respiration is manifested.* These belong to the following 

 classes and major groups: 

 Vermes : 

 Rotifera. 

 Gephyrea. 

 OUgocUceta-Limicola. 



ECHINODEKMATA : 



Holothuroidea. 

 Arthropoda : 



Crustacea (generally). 



Insecta (aquatic larvae generally). 



MOLLUSOA : 

 Dentalium. 



PHOSPHORESCENCE IN ANIMALS. 



Mons, Jousset dc Bellesme has continued his researches upon tlie phos- 

 phorescence of animals by a special investigation of that of the glow- 

 worm.t He concludes that the phosphorescent substance is probably a 

 gaseous product, for the structure of the giand does not give us the idea 

 of an organ with a liquid secretion. The chemical products which are
