SPONGILLA LORDII. , 81 
‘This speciesis interesting, from its close alliance 
in structure to the European type of this genus, 
and from the very slight structural resemblance 
it has to the numerous species of the Amazon 
river; the principal character by which it is 
connected with the latter series of species being 
the mode of the congregation and disposition 
on its basal membrane of its very numerous 
ovaries. 
‘T have dedicated this species to Mr. J. K. Lord, 
as a slight acknowledgment of the good services 
he has done to science by the collection of this 
and numerous other valuable specimens of Na- 
tural History, from the unfrequented regions 
which he has explored.’
