Schizomavella auriculata acuta new variety 

 Plate 38, figs. 7-9 



This rather characteristic variety differs but little from the typical 

 auriculata except in the nature of the avicularia. These are usually 

 mounted on a low umbo with the sharp-pointed mandible directed back- 

 ward, they are less elevated than in the typical form, occasionally 

 enlarged ; on the same colony there are more rarely very elongate slender 

 avicularia, pointed at both ends, with the mandible occupying only 

 about half of the avicularian area. These elongate avicularia are little 

 elevated and horizontal with the frontal ; they resemble the giant 

 avicularia of the variety ochracea Hincks, except for their form and 

 position of attachment of the mandible. The frontal is usually thickly 

 granulated with small round tubercles between the pores. The zoarium 

 is encrusting and varies from white to reddish brown in color. 



At first I believed this to be a different species, but the inter- 

 gradations and the similarity of the operculum and ovicell seem to 

 rank it as merely another variety of auriculata.
