Color, olive brown (olive green, according to Lampert). A single 

 madreporic canal and three Polian vesicles present. Deposits: Numer- 

 ous C-shaped bodies; tables similar to the small tables of the following 

 species, the truncate spire ending in eight to twelve, or even fourteen, 

 teeth. Disk of tables small. Few incomplete rosettes are present. 

 The pedicels contain spinous rods, very similar to those of S. tropi- 

 calh. The dorsal appendages are also strengthened by numerous 

 curved, simple or branched rods. Rosettes are not recorded in typ- 

 ical examples. 



The following is the distribution of this species as given b}' Theel 

 and Lampert: Zanzibar (Selenka), Querimba and Mozambique (Sem-

Body cylindrical, elongate, flattened ventrally, arched dorsally, 

 anteriorl}^ untapered; slightly tapered l)ut truncate posteriorl3^ 

 Mouth anterior but ventral, surrounded by a fringed papillose collar; 

 anus posterior. Mouth large; circle of tentacles, 20 in number, Ijroad, 

 Tentacles rather short; peltate; the crown convex. Pedicels numerous, 

 disposed in three longitudinal bands on ventral surface, the median 

 band twice as wide as the laterals. Papillee scattered over dorsal sur- 

 face. There are four rows (irregular) of very prominent protuber- 

 ances, nearly as large as a small acorn in the living animal, a series 

 along either side adjacent to ventral surface, and a row on both dorsal 

 ambulacra. Small papilla?- scattered over the interambulacra. 

 Integument thick, very minutely roughened ])y spires of tables, 

 especially on the conical protuberances, where the large tables are 

 abundant. Deposits: Remarkably large robust tables with a conical 

 spire ending in a single point, and much smaller tables of two or three 

 sizes, with a small disk and a truncate spire terminating in eight to 

 twelve points; besides these, C-shaped bodies and small dichotomously 

 branched rods. In the pedicels and papilla? robust supporting rods, 

 dilated and perforated at the middle. Color in life, tentacles, pale 

 greenish gray to whitish; body dark olive green mottled with deep 

 brownish green; in alcohol, dull j'-ellow ocher. Length of preserved 

 specimen, 160 mm.; breadth at anterior end, 32 mm.
