are the filamentous appendages to the mantle of the latter ; inter- 

 mediate forms appearing unknown. 



Now the present species presents at certain times these filaments 

 developed from its mantle ; and also presents on those parts of its 

 body where the tubercles want these filaments, the singular black 

 " cells of pigment," noticed by Dr. Stoliczka. 



A careful examination of several living specimens has afforded 

 me the following additional data on the subject : 



That in the present species, the tubercles, when plain, are stud- 

 ded with black points, in varying number. 



That when the tubercles develop filaments, these occur similar- 

 ly to the black points. 



That the black points sometimes show a tendency to become rais- 

 ed on stalks. 



That the filaments disappear in confinement, or in alcohol ; and 

 that they only occur partially, and in some specimens only, while 

 others at the same locality and season want them. 



Not being able to keep vivaria I have not ascertained whether the 

 filaments disappear permanently or temporarily, how they so dis- 

 appear and whether they are replaced by black points ,* but I think 

 enough is noted to establish the fact that the black points or cells 

 become developed at seasons, or in specimens, into filaments ; and 

 thence Peronia cannot be separated from Onchidium, unless on cha- 

 racters distinct from those already quoted. 



Y. Extracts from a Diary written on the occasion of a visit to 

 K'harakpur and Munghir. By Ba'bu Eashbeha'ry Bose. 



Several extracts from the paper were read referring to the 

 Mosque of Lak'hinpur, the conversion to Islam of one of the 

 Kajahs of Kharakpur, and the legend of the Five Virgins who 

 threw themselves from the hill, which in remembrance of them is 

 called 'Panch Kumari.' 



The paper will be published in the first number of the Journal 

 for next year.
