 enlarged and branched, but never perforated. 



Leptosynapta irregularis is characterized by the brown warts on

the body, by the irregular shape of the anchor-plates and by the 

 smooth and slender rods in the digits, and it may by these charac-

Epitomapta n. g. 

 Genotype: Epitomapta tabogae n. sp. 



Diagnosis: Tentacles pinnate, usually twelve. Sense organs 

 never in the form of pigment-eyes, but occur as sensory cups on 

 the oral side of the tentacles. Calcareous ring well developed. The 

 radial pieces are not perforated for the nerves, but with a notch 

 in the anterior margin. Cartilaginous ring wanting. Polian vesicle 

 and stone-canal single. Stone-canal unbranched. Ciliated funnels 

 are of different shape and only found on the body-wall, not on 

 the mesenteries. 



The calcareous deposits in the body-wall are anchors, anchor- 

 plates and miliary granules, in the tentacles rather large rods. The 

 stock of the anchors is finely toothed and the vertex is smooth. 

 The anchor-arms are in the posterior end of body distinctly serrate, 

 in the anterior end of body usually smooth. The anchor-plates have 

 seven large holes in the anterior end and a varying number of
