History.- — Glyplometra timorensis was described in 1912 on the basis of four speci- 

 mens from Siboga station 297. It was referred to Perissometra on the establishment of 

 that genus in 1916. In my memoir on the unstalked crinoids of the Siboga Expedition 

 published in 1918 Perissometra timorensis was described in detail and figured. In 1928 

 Prof. Torsten Gislen wrote that timorensis, together with patula, lata,flexilis, and aranea 

 (=Parametra orion), should be included in the genus Perissometra, whereas all Perisso- 

 metras with the IIBr series 4(3 + 4) ought to be referred to Crossometra.

Diagnostic features. — A highly ornamented rather small ami slender species; tho 

 ossicles of (lie division series and earlier brachials have abruptly everted borders, a low, 

 narrow, sharp, and prominent median keel, and more or less numerous small beady 

 tubercles or capitate spines scattered over the dorsal surface; the 10-18 (usually 10-12) 

 arms are 100-140 mm. long; the IIBr series are 4(3 + 4) or 2; and the cirri, which are 

 arranged in 10 rows on the centrodorsal, have 11-15 rather long segments.
