 Tin- Large and extremely delicate Bpeciee is close to C. / ilguralis Brun,* and to C. 

 diorama Schmidt ; < the chief mark of distinction being the far more rapid increa 

 the areolal ion from the center outward, and the consequently more robust size of the 

 network in the Last-named forms.

 tion of Schmidt's At la- it is credited to Schmidt, a- well as in tin- not.- of Hat tray'.- in

 My specimens are with very obscure apiculae or wholly without them, a condition 

 noted by Rattray. The specimen from -tat ion 3669B is placed here with some doubt. 

 The beads are slightly oval. It is nearest to the unnamed figure,** on which Schmidt < 

 ha- given reasons for withholding from this species. Rattray erroneously refers 

 ure f to this species to which Janisch gives the name C. atlanticus i rrun.,0 which should 

 probably be ( '. atlanti* us < lastr. a- figured in the subspecies,' a form recognized a- valid 

 by Rattray. 



Found at Btations 2844, 3526, 3571H, 3607, 3669H, Aleutian Islands, Bering - 

 Pribilof and Commander Islands, and along Kuril Chain.
