Sycortusa Haeckel [1872]. 



Type species S. Icevigata Haeckel, {^Grantia Icevigata). 

 One of the subgenera into which Haeckel divided his genus 

 Sycortis, raised by von Lendenfeld [1891] to generic rank. 



Sycothamnus Haeckel [1870]. 



Type species S.fruticosus Haeckel, (=; Leucetta primigenia). 



Sycum Haeckel [1870]. 



Type species S. ciliatum Fabricius, (^^Sycon ciliatum). 

 A modification of Risso's generic name Sycon for which there 

 does not seem to have been any adequate reason. 



tSYCUBUS Haeckel [1872]. 



Type species S. primitivus Haeckel, (=Sycetta primitiva). 



Tarroma Haeckel [1870]. 



Type species T. canariense Michlucho-Maclay, { = Leuco- 

 solenia canariensis). 



Tarropsis Haeckel [1872]. 



Type species T. coriacea Montagu, (^Leiocosolenia coriacea). 



Tarrus Haeckel [1870]. 



Type species T. clensihs Haeckel, {=Leitcosolenia clensa). 



Teicpionella Carter [1878]. 



Type species T. prolifera Carter, {= Leucetta prolifera). 

 A genus proposed by Carter for two species, whose slight 

 similarity of external form misled him into thus associating them. 

 One of these has now been placed by us in the genus Leucetta, 

 the other is the type of our genvis Teiclionojjsis. For a criticism 

 of the genus Teichonella and its species see Dendy [1891 B]. 



Tenthrenodes Jenkin [1908 B]. 



Type species T. antarcticas Jenkin, (^^ Sycon antarcticuon). 

 For a discussion of this genus and its species see under Sycon 

 (p. 744). 



Thecobietra Haeckel [1870]. 



Type species T. loculosa Haeckel, [ = Letccosolenia loculosci). 



Utella Bendy [1892 B]. 



Type species U. hystrix Haeckel, { = Sycodorus hystrix). 

 We have found it necessary to substitute HaeckeFs name 

 Sycodorus for the above. 



VosMAERiA von Lendenfeld [1885 B]. 



Type species V. gracilis von Lendenfeld, {^^Grantia gracilis). 

 One of the genera based by von Lendenfeld on the presence of
