there is an extremely short third segment with rudiments of the 
small, bud-like third pair of uropods. First and second pairs of 
uropods are well developed, but the inner rami in both pairs small 
and spiniform. There is no trace of telson. The side plates of third 
to sixth pairs of pereiopods, especially those of the fourth pair, are 
very large and contribute to the forming of the globe. 
Through its globular shape this new forms recalls the Hyperid 
Mimonectes (see Bovallius: Mimonectes, a remarkable genus of

the eggs in the marsupium.

nectes the globe is shaped partly of quite other segments, the 
enormous head and the two first segments making the half of the 
globe, while in Danaella the head and these two segments are of 
no importance in the forming of the globe. Here-to comes that 
in Mimonectes the ventral side of the mesosome is the ventral side 
of the globe; but this is not the case in Danaella, for here the 
globe is hollow, thé ventral side of the mesosome lying far dor- 
sally of the centre of the globe (see fig. 1 : the schematic trans¬ 
versal section). There are several other differences, for example: 
the side plates small in Mimonectes, large (at all events some of
