Yon Lendenfeld (10) gives a diagnosis of the genus Stelletta and its 
characteristics. 
Topsent (6) gives definitions of the genera Dendoryx , Amorphina, and 
Reniera (pp. 120 & 121). He divides the genus Cliona into Euclionce and 
Paraclionce. In the former the three kinds of spicules, or as many of 
them as may be present, retain their typical form ; in the latter, one of 
them is modified in form. 
(6) New, emended, or redescribed species. 
Amorphina connexa , ? n. sp., an Amorphina angulata typica ; Topsent, (6) 
pp. 144 & 145, pi. vi, fig. 15. The author concludes that: (1) either there 
is a single species, Amorphina angulata , of which Bowerbank’s two species 
( Ilalichondria angulata and H. couchii ) are varieties ; or, (2) there are 
three distinct species — Amorphina angulata , A. couchii , and A. connexa ,
