Studer (1887) gives the only satisfactory definition of this genus that 1 have been 

 able to find. The following is a translation : 



"Stem upright, branched, with thin ccenenchyma and exserted calyces which stand vertically 

 and have their ends truncated. Calyces lateral on stem and branches, leaving a median space 

 bare. The spicules form an otiter layer of small doublé clubs and an inner layer of longer 

 cylindrical or spindle forms, thickly covered with verrucae". 



Wright and Studer (18S9) give practically the same definition as the one quoted above. 



With the single change of the words "doublé clubs" to "doublé heads" the definition 

 as given by Studer can stand as acceptible for our present purpose. 



The type of this genus appears to lic Nicella dichotoma (Gray) '. Dut two other species 

 of the genus seem to have been described, i. e. Nicella pustu/osa and N. rcticulata. both by 

 Tm and Simpson. It seems. however, from the descriptions and figures, that neither of 



these species can be regarded as belonging to this genus as defined by Studer.
