A ROYAL GIFT 29 
for a Schizopod.’ It is also said that ‘this form ranks, 
therefore, as the largest by far of all hitherto known 
Schizopods,’ although in truth an allied species in the 
same genus, Gnathophausia gigas, v. Willemoes Suhm, 
obtained by the Challenger from a depth of 2,200 
fathoms, measures 142 mm., or 52 inches. Both of these 
species, with one or two others in the same genus, such as 
Gnathophausia Goliath, A. Milne-Edwards, far surpass 
most of those in the sub-order, the length usually ranging 
from half an inch to two inches. 
Of the Stomatopoda, some are no more than three- 
quarters of an inch in length, but of the species Lysio- 
squilla maculata (Fabricius), a male specimen, presented 
to the naturalists of the Challenger by the King of 
Amboina, fell short only by three-sixteenths of an inch 
of measuring a whole foot. 
The Cumacea are a feeble folk. In some species the 
slender frame, with trunk and tail and tail appendages all 
told, does not exceed, or even equal, a twelfth of an inch. 
Only the arctic Diastylis Goodsiri (Bell), occasionally yields 
a Goliath of an inch and two-fifths. In the Isopoda there 
is a far greater range of size. Within a single genus, 
Hurycipe mutica, Sars, which measures about one milli- 
métre and a third, is contrasted with Hurycope gigantéa, 
Sars, which reaches 535 millimétres, or about an inch 
and a third. Anilocra gigantea (Herklots), measuring 
three inches and a third, would seem a veritable monster 
in this sub-order, were it not far surpassed by the ex- 
tremely exceptional Buthynomus giganteus of Alphonse 
- Milne-Edwards, which is nine inches long by four inches 
broad.!. This prize was fished up by the United States 
Survey steamer Blake, under the supervision of Alex. 
Agassiz, from a depth of 955 fathoms, in the region of the 
Gulf Stream, to the north-east of the bank of Yucatan 
to the north of the Tortugas. Among the Amphipoda, 
none yet discovered reach more than about half the dimen- 
sions of this great Isopod. At the other end of the scale
