All figures from unretouched photographs of specimens preserved in formol. 

 Fig. 1. Ptychogena erythrogonon, sp. nov. ; oral view of a mature specimen 30 mm. in 



diameter. 

 Fig. 2. Eutima levuka, immature specimen ; side view. X 4. 

 Fig. 3. Eutima levuka ; oral view of another specimen, showing four large tentacles, and 



the form of the peduncle and manubrium, x 4. 

 Fig. 4. Sibogita simulans, sp. nov. ; side view of type. X 1.5. 

 Fig. 5. Aboral view of the same specimen. The blind terminations of seven of the eight 



adradial canals are clearly visible. The lateral flattening of the bell is normal, 



and was observed in life. 

 Fig. 6. Phialucium comata, sp. nov. ; oral view of type specimen 7.6 mm. in diameter. 

 Fig. 7. Side view of same specimen. This photograph gives a good idea of the form of 



the bell in life, as well as of the extent of the gonads along the radial canals. 

 Fig. 8. Eutimalphes scintillans, sp. nov. ; side view of type specimen 10 mm. in diameter, 



showing form of bell, peduncle and manubrium, and location of gonads on 



radial canals. 

 Fig. 9. Eutimalphes scintillans ; oral view of another specimen of about the same size.
