Figure 23. — Cryptophialus longicollatus Berndt, 1907a (after 

 Berndt 1907a). 



Berndt describes this species from 45 to 50 specimens from two 

 shells. The mantle opening lies on a long, attenuated process, which is 

 up to one-third as long as the entire animal. The labrum and cirri 

 are correspondingly longer, extending to the mantle opening. On each 

 side of the mantle openings are two-jointed, especially strong spines, 

 the basal joint being bristled.
