Trinchese, 1877-79
Ratio of foot-width to body-length in life 1 : 8 up to 1 : 20. The rhinophores are elongated and usually inrolled. Through the translucent skin a delicate pair of lateral digestive channels and their ramifying tributaries can be clearly seen. Foot rounded antero-laterally (propodial tentacles are lacking).
Worn radula teeth do not drop from the radula ribbon into the ascus sac, but form a continuous spiral series. The anus is median, antero-dorsal. A minute spine is sometimes present on the penis.
Cerata also contain tributaries of the albumen gland.
