practicable alteration, such as the addition of us, if no 

 acknowledged Latin form already exists. Hence the family 

 names Brown and Smith should be Brownius and Smithius ; 

 but (and from the point of view of scientific species names 

 this is the important fact) the genitives of names ending in 

 ius should properly be written to end in i only, not in ii ; thus, 

 the genitive of Cains is Gai, of Smithius Smithi, and as this 

 is the case usually in question, the matter seems to be resolved 

 thereby." 



Finally, the author would gratefully welcome any obser- 

 vations or information any of his readers may be disposed to 

 offer him, and especially specimens of the rarer species. 

 Should the volume ever deserve a second edition, the infor- 

 mation so acquired would be added with acknowledgments. 

 The collector should realize that the value of any specimen 

 is greatly enhanced by a record of its locality and date of 

 capture. A piece of paper with these entries written in 

 ordinary lead pencil should be attached to each specimen. 

 Letters or specimens sent to the Honorary Secretary of the 

 Bombay Natural History Society, 6 Apollo St., Bombay, 

 would be forwarded.
