REPORT ON THE HEXACTINELLIDA. 391 



knob, frequently with a transverse ring of teeth. The gastral clavula; are ahnost always 

 well-developed, verticillate forms, with convex marginally toothed terminal disc and a 

 very variable number of teeth. Sagami Bay, Japan, 100 to 200 fathoms; west of 

 Manila, 700 fathoms. 



Species 2. Farrea sollasii, n. sp. 



The parenchyma contains discohexasters with short principal rays and long delicate 

 gently diverging terminals. They otherwise closely resemble Farrea occa. Sagami Bay, 

 Japan, 100 to 200 fathoms. 



Species 3, Farrea vosmaeri, n. sp. 



The parenchyma contains strongly developed oxyhexasters with long and strong 

 principal rays, and four short, markedly divergent, usually somewhat outward bent terminals. 

 Discohexasters also occur with short principal rays and weakly developed long terminals, 

 as also discohexasters with somewhat strongly developed, long principals, each with four 

 short S-shaped terminals disposed in a cup-like form, and bearing terminal knobs. 

 Sagami Bay, Japan, 100 to 200 fathoms. 



Species 4. Farrea clavigera, n. sp. 



A straight main tube rising at right angles gives off transverse and terminal, 

 branched and anastomosing secondary tubes. The parenchyma contains oxyhex- 

 asters with long principal rays, each bearing four markedly diverging terminals. The 

 dermal clavulse always exhibit a club-shaped distal end, which is sometimes elongjited 

 and quite smooth, in other cases compressed and weakly developed, and provided with 

 a simple or double transverse circle of hooks. The gastral clavulas all exhibit four 

 cruciately disposed, much recurved anchor teeth. Near the Banda Islands, 200 to 360 

 fathoms. 



Subtribe II. Scopularia, F. E. S. 

 Besides the hypodermal and hypogastral pentacts radially disposed scopulse occur. 



Family I. E u R E T i d .^, F. E. S. 



Branched and manifoldly anastomosing tubes, whicli either form an irregular frame- 

 work or the lateral wall of a cup. The dictyonal framework in the tubular wall always
