beam, and terminatiiia- in about ten teeth. Buttons smooth. Among 

 the buttons many rods and C-shaped bodies. Radialia of calcai'eous 

 ring- much higher than interradialia. One Polian vesicle, one madre- 

 poric canal in dorsal mesenter}'; gonad branched. Color in alcohol 

 (Sluiter) yellowish gra}^ darker brown at either end; pedicels and 

 papilla^ yellowish or bright reddish brown, ventral surface brighter 

 than dorsal, and darker at anterior end. 



This species was not secured by the Alhatt'i^xx expedition, which is 

 to be regretted, since the type locality is the "Sandwich Islands." 

 Sluiter " unites i<emperianu7n, selenJilan tint , and diihfoswn . The deposits 

 appear to be more or less variable. The same animal will possess 

 tables with well-developed and small disks, the former having six or 

 seven large holes. The so-called buttons are not typical, but rather 

 to be considered perforated plates with several corners. 



If these three forms represent a single species, it thus ranges from 

 the Hawaiian Island.s to Tahiti and Fiji Islands, and into the Kast 

 Indies (Sluiter: Sel)a. Pulu-Passi-Tanette, Rotti, Timor, Salyer, Elat).
