1908| Decapod Urustaceans. 11 
times two large spines, and two diverging rows of spinules: and on 
the outer edge, somewhat more distally there are two large spines 
and å somewhat incomplete row of spinules. Carpos has only å 
weak armature of spines. 
Propodos is everywhere covered with numerous blunt spinules 
which are rather larger and sharper along the exterior side than 
on the broad upper and under surfaces. On the greater portion 
of the interior side the armature is sparse. 
The anteriorly-directed finger-shaped prolongation (*61/>” Sr. B.) 
has on the edge confronting the dactylos å row of knobby teeth 
of which the middle one is the largest. Digitus is gradually and 
rather sharply curved, only slightly longer than the finger-shaped 
prolongation of the propodos, and has like it å row of knobby teeth. 
2nd Pereiopod (fig. 2, VI) is considerably shorter than the 1st 
 pereiopod, only reaching forward to its carpos. The total length of 
the 2nd pereiopod in å speecimen 57 mm. long was 22 mm. The right 
and left pereiopods are of equal length and are both provided with 
ehelae. Propodos and carpos are together of the same length as 
meros, ischium nearly of the same length as carpos. Basis, ischium 
and meros are each furnished on the inner side with a largish spine, 
and in the case of the last two joints supplied also with some 
smaller spines. The other joints have no corresponding armature. 
Digitus is only slightly curved and terminates in å sharp tip, as 
does also the finger-shaped prolongation of the propodos. Moreover 
both the latter and the digitus have their confronting edges sup- 
plied with å row of regular small pointed teeth. 
3rd Pereiopod (fig. 3, VI), 28 mm. long in å 57 mm. specimen, 
reaches almost to the articulation between carpos and propodos and 
is the next-longest pereiopod after the 1st. The length of the joints 
in their relation to one another is approximately the same as is found 
in the case of the preceding pereiopods, meros being considerably 
longer than any of the remainder. Dactylos is flattish, blade-shaped 
and densely setose, and propodos is also lavishly furnished with 
setae; but the remaining joints on the contrary are very sparsely 
supplied with them. | 
4th Pereiopod, 25 mm., being thus several millimeters shorter 
than the 3rd pereiopod though practically of the same breadth.
