Rijksmuseum Van Natuurlijke Historie, Leiden, 2 paratypes; Pacific 

 Marine Station, 3 paratypes. Ace. Xo. 1330 Arth. 



Remarks: This species differs from Caecianiropsis ectiformis (Van- 

 hoffen), its closest known relative, in having spinelike teeth on the 

 posterolateral borders of the pleotelson. Such teeth appear lacking 

 in that species.
