NATUEAL HISTOEY.

during the day from the heat of the sand, these singular 
lumps are full of the windings of the worm. 
Hirudo, ngata, leech, a small one is found in most lakes 
and ponds, it is about a quarter of the size of the medicinal 
one, which appears to possess all the blood-sucking powers 
of the European kind, and doubtless might be used for that 
purpose. In the waters where it is found, bathers frequently 
find them on their legs. 
There is a considerable variety of land leeches : one is of 
a bright red color, another of a pale buff, a third deep 
chocolate, a fourth a chocolate with a yellow border ; they 
are found under stones and decayed timber, and seem to be 
perfectly harmless. 
Fam. Branchiopopodea apus cly clops. This singular en- 
tomostraca attains a size of two inches in length, and is very 
rarely seen, but then it appears in large numbers. 
Such is a faint outline of the Zoology of these Islands, in a 
brief essay nothing more can be attempted ; much of necessity 
must be omitted of what is imperfectly known, and still more 
remains to be discovered ; but sufficient, perhaps, has been 
written to invite further and more extended investigation, 
and more than enough to show that the Natural History of 
New Zealand will amply repay such trouble being bestowed 
upon it.
