11. Tarandichthys filamentosus (Gilbert). Plate xxviii. 



Icelinus filamentoms Gilbert, Proc. U.S.Nat. Mus., 1890, 85. Off 

 Santa Barbara Islands. 



The section of Icelinus distinguished by the presence 

 of filamentous dorsal spines, and the presence of bony 

 plates behind the pectoral, represents a subgenus or genus 

 distinct from Icelinus. This may be called Tarandich- 

 thys, Jordan & Evermann. The name (Tapdvdos, rein- 

 deer) alludes to the antler-like preopercular spine. The 

 accompanying plate is from one of the type specimens 

 of the type-species, filamentosus. 



12. Icelinus quadriseriatus (Lockington). Plate xxix. 

 We present for comparison a figure of the type-species 



of Icelinus from a specimen dredged off the coast of 

 California.
