DIAGNOSES OF THE FAMILIES, GENERA AND SPECIES. llo 



Caulophacus Joti folium n. sp. — Caulopltacys with inverted- 

 conical body, continued below into a long stalk. Dermalia and 

 gastralia, hexactinie ; the former with a spindle-shaped, and the 

 latter with a slender, elongate, pinular ray. On the lower part 

 of the stalk the dermalia lose the proximal ray, while the distal 

 ray assumes a club-like or balloon-like shape. Spherical disco- 

 hexasters (60-115/^- dia.) with thick, ])arbed terminals ; sometimes 

 hemihexactinose or hexactinose ; they lead by gradual transition 

 into much thinner-rayed, onychaster-like forms. Without lopho- 

 discohexaster. 



SYMPAGELLA O. ScHM. 



Caulophacids of cup-like body, showing tendency to form small 

 colony by budding. Parenchymalia as in Caulophacus. Dermalia, 

 either hexactinie or pentactinic pinnies. Gastralia, hexactinie 

 pinnies. Besides discohexasters, strobiloplumicome always present. 



For a key to species referred to this genus, see p. 97. 



Sympagella anomala n. sp. — Sympagella with irregularly- 

 shaped body, composed of a small number of incompletely divided 

 persons in each of which an osculum opens at the upper end ; 

 stalk multiple, or branched and anastomosing. Both dermalia 

 and gastralia, hexactinie ; similarly developed, though the former 

 is much stouter ; pinular ray, spindle-like. Discohexaster, mainly 

 an onychaster-like form (up too 100,« dia.) in which the ter- 

 minals are finely attenuated towards the end and bear at the 

 point 2-6, short and exceedingly fine branchlets in forwardly 

 and outwardly directed (not retroverted) arrangement. Strobilo- 

 plumiçonie of the usual shape and structure.
