surfa ■ distant thorn-like projections to proportionally very heavy and coarse spindles 



with surfa ed with coarse, irregularly warty tubercles. There are also many oval spicules, 



such as itnmon in this Family, truc clubs and a few irregularly branched forms. 



Rarely, girdled spindles and irregular crosses are seen, such as are figured by Kollker, 

 the original describtr of tin- species. 



• lor. The colony is a dark, rather deep red; the polyps yellowish and the spicules 

 red and white. 



General distribution. Type locality, "Bohol", Köluker. 



Another specimen from the same station is pale in color and some <>i the polyps are 

 completely retracted. 



2. Setnperina brunnea new species. (Plate II, figs. 2, 2,1; Plate XI, fig. 3). 



Stat. 273. Anchorage off Pulu Jedan. [3 meters. Sand and shells. 



St.it. 104. 1 42.5 S., 130°47 .5 E. 32 meters. Sand, small stones and shells. 



The colony is branched, rndely flabellate in form, 20.5 cm. in height and with a 

 spread of about S cm. The base is lacking. The main stem is approximately round in section, 

 .in. long to first branch, and 8 mm. in diameter. Alter giving off three stubs of branches 

 it sends off a compound branch with four branchlets. 1.5 cm. above this it forks into two 

 approximately equal branches each of which again branches dichotomously, one quite regularly 

 so. until branchings of the 4 th order are attained. All of the branches are round in section 

 and more or less clavate at the ends. The main branches are about 5 mm. in diameter, the 

 secondary branches about 4 mm., and the distal twigs 3 mm. At some of the furcations on 

 the distal parts of the colony there is a membranedike expansion or web of the ccenenchyma 

 which fills in the amde sometimes as much as S mm. above the actual angd.e of the fork. The 

 calyces are on three sides of the stem and branches, leaving the fourth side comparatively bare. 

 On the other three sides the calyces are thickly and regularly implanted about 1.3111111. apart. 



The individual calyces are low dome-shaped verruca; which vary greatly in height with 

 the degree of expansion of the polyps. A typical one measures 2 mm. in diameter, and the 

 upper parts of the walls are strongly 8-lobed and covered with coarsely tuberculate spindles 

 and short oval forms. The polyps are completely retractile and very strongly spiculated. The 

 collaret is composed of about 6 rows of encircling spindles which assume an en chevron 

 arrangement on the tectacle bases. The distal part of each tentacle bears a strong bami of 

 longitudinal spindles which seem to encrust it to its tip. 



Spicules. These are of the ustial type tor the genus. The axis bears relatively few 

 r rod-like forms with distant spiny points, and relatively numerous strongly tuber- 

 culate spindles in which the tubercles an- fairly distant on tin- slender forms and much crowded 

 and irregular on the stouter forms. These intergrade with stout oval spindles covered with a 

 compact mass of tubercles. The spicules of the ccenenchyma do not differ appreciably from 

 Reis.
