 both mandibles ; base of upper, and a larger portion ol base of under

 but less clouded with brown. In this individual, also, large patches 

 on the feathers beneath the wings are covered with the ova of parasites. 



1 am unwilling to resume my monthly notes without apologising to 

 my ornithological friends for having left many kind letters unanswered. 

 Hdving mentioned to the Editor, in a private communication, the 

 cause of ray late temporary abandonment of my favourite pursuit, I 

 can only trust that by inserting this he will signify his belief tliHt, 

 notwithstanding my long silence, my good wishes for the ' Zoologist' 

 and its readers still continue unabated.

Marine Animals in P'resh iValer—A SDinewhat personal discussion has recently 

 taken place in liie columns of the ' Aihenaeum ' belAcen Dr. WuUicli and Cul. Stuart 

 VVorlley respectiiif; the possibility of cleanint; the slieeling of foul ships by a temporary 

 itnnicrsion in fiesb water. The practicability of this proceedinf; is slotitly denied by 

 Col. Wortley, whose views are ably supported by Mt. W. A. Lloyd, of the IJaiuIiurg 

 Aquarium. In his last letter published in the ' Athenecuui' of this wetk, Mr. Lloyd 

 gives the following inieresiin^ details respecting the residence of toarine animals in 

 tresli water, and al.so regarding the residence of rre.>.li-watcr animals iu sea Water :^ — 

 ''The abstract fact of certain marine animals being able to live occasionally or 

 eniirely in fresh water, is an interesting one, apart from iis direct coinmeicial bear- 

 iiigs. We all know that the salmon, which breeds in rivers, goes into the sea to feed, 

 u'.id that the smelt, which is reganled as a sea fish, not o ily visits riveiB during 

 certain periods of the year for spawning purposes, but that it hai> been kept for years 

 coiiiinuou<ly iu a fresh-water pond without ever ^oing to sea, and that under these 

 circumstances it has thriven well, has abundantly multiplied, and has not deteriorated 

 for table purposes. So, too, the sturgeon, which lives in the sea, and at great depths, 

 is found commonly in rivers of the Continent of Europe; and more than thai, it has 

 been kept for years in freshwater ])onds in the Zoological Gardens of London and 

 Hamburg. In the ialter place it has giov)n amazingly as well, and with it there is 

 now, in the same pond, a large sea lamprey (Pelromyzim marinus.) This lamj)rey has 

 been iu ihc jinnd since ISUo, and jci (on the authority of Mr. L. Lloyd, the cxcclleul
