64 Miscellaneous. 



by a general description of the structure of fishes and its modifica- 

 tions in the various groups, leading up to a notice of the reproductive 

 phenomena presented by animals of this class, and their growth and 

 variation during development. Other chapters are devoted to the 

 distribution of fishes in time and space, the latter subject treated at 

 very considerable length, and the whole winding up with a notice of 

 those deep-sea fishes our knowledge of which is mainly due to the 

 dredging-operations of the last few years. The remainder of the 

 volume (more than half) is devoted to systematic ichthyology, and 

 gives the characters of the orders and families and of the principal 

 genera, with notes on the more important points in their natural 

 history. The volume is very freely iUastrated. 



MISCELLANEOUS. 



On a nevj Species of Papilio from South India, with EemarJcs 

 on the Species allied thereto. By J. Wood-Mason. 



In December last the Indian Museum received from Mr. F. W. 

 Bourdillon, of Trevandrum, a small collection of diurnal Lepido- 

 ptera, amongst which was a much-worn and tattered example of a 

 female insect, evidently closely allied to the North-Indian P. Castor 

 and to the Burmese P. Mahadeva, with the same sex of the latter 

 of which it turned out on examination to agree in having the discal 

 markings of the hind wing confined to the median region of the 

 organ, where they form a transverse band of lanceolate spots, 

 instead of being diffused over the whole disk and extending into the 

 cell, as in the former. 



About a month ago a few species of butterflies were received 

 from Mr. G. H. Kearney, of the Berkodee Coffee-Estate, Koppa 

 Anche, Mysore ; and amongst them is a fine specimen of the male, 

 which proves that the species is, as the above-mentioned female 

 specimen had already indicated, more nearly related to P. Mahadeva 

 than to P. Castor, and enables me to describe it. 



Papilio Dravidarum* , n. sp. 



Allied to P. Castor and to P. Mahadeva t, but more closely so to 

 the latter, with which it agrees in the form of the wings in both 

 sexes. 



Sexes alike, having not only the same form of wings, but also the 

 same general type of coloration as the female of the two described 

 species, the male differing from the female only in the darker and 

 richer tints of its upper surface. 



(S . Upperside rich fuscous, of a much lighter shade than in 



* DravidcB -arum) from Z)rat7V7a= common name of South-Indian 

 peoples.
