 new genus. Spmnilax. 



3. Subgenus Steiniella (Schiitt) Kofoid, subgen. nov. 

 Body rounded, spheroidal or subpolyhedral. exceedingly fra- 

 gile, closing platelet of apex carried t)ver upon dorsal side. Sur- 

 face markings tending to longitudinal direction.

Gonyaulax liyalina Ostenfeld og Schmidt (1901), p. 172, figs. 24 a-d. 

 Gonyaulax fragilis (Schiitt), described as Steiniella fragilis by 



Schutt (1895), p. 6, figs. 26 i.„. 

 Gonyaulax inflata (Kofoid). Described as Steiniella inflata by 



Kofoid (1907a), pp. 168-169, pi. 2, fig. 15. 

 Gonyaulax mitra (Schiitt). Described as Steiniella mitra by Schutt 

 (1895), pi. 7, figs. 27 ,-,.,. Possibly not a Steiniella. 



4. Subgenus Acanthogonyaulax subgen. nov. 

 Characterized by spines upon the hypotheca with axial cores 

 similar to those of Ceratocorys. Girdle premedian. Plates of 

 aj)ical region numerous (6 in 6'. ccraiocoroide.^i). Contains one 

 species G. ceratocoroides (Murr. and Whitt.) Kofoid (1910, p. 

 182). 



For convenience in reference I append herewith (1) a list 

 of species of Gonyaula.ic regarded by me as synonyms, (2) a list 

 of described species which I regard as indeterminable and there- 

 fore invalid, (3) a list of species originally described in other 

 genera which are here included in the genus Gonyaiila.r, and (4) 

 species referred to Gonyaula.c but belonging to other genera.
