SPONGILLA LORDII. 81 



'This species is 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. 



' I 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.'
