In all these specimens one finds the variable appearance of the 

 cirri peculiar to G. sokisier. The only difference from the specimens 

 described by A. H. Claek is the number of C, which in the Bockian 

 species are more numerous and arranged in 2 to 3 whorls. The above- 

 described specimens miglil peihaps therefore be characterized as a 

 forma mnUicirra.

 From St. J4 (2 .sp.). 15 (1) |1S(1)] = 4 specimens. 



Sp. 1 (St. 14) Cd almost iiemispherical, 9 mm., free dorsal pole 

 5 mm., a little hollowed in the middle. C. XXXVIIJ 28—33: 30-36 

 mm. in 2 whorls. 1''' and 2'' segments short, 3"^ to 5"' cubical or 

 somewhat longer., 6*'' — 10"' segment L = 1 V2 br. Distal ones L = V2 X br. 

 Dorsal prominences from the 15"' to 20"' segments, L = + \5 of Ihe br 

 of the cirral. A Aveak opposing spine. Tei-minal claw slightly curved. 

 L = 1 \/2 X the preceding segment. 



R — s slightly visible at the corners. I Br 1 h = V14 br, in the 

 basal half united with each other. Between them a depression in the 

 perisome. I Brax h = ' 3 x br, pentagonal, the distal margins slightly 

 concave. The br 6,.^ — 7 mm. Primipostaxillaries united inside. On 

 their distal, interdistichal ' side a depression as between the primi- 

 brachial series. Divisions-series broad, smooth, flattened, but the pe- 

 risome between them is quite visible. The distance between II Br 3 in 

 two different division-series is 3,.-. mm. Disk reaching to II Bi- 2 or 3. 

 II and III Br— s:4 (3 + 4). Arms XXXVIII 125 mm. +, very fragile. 

 Br-segments distally somewhat, but only slightly, thickened. Syzygies 

 distally with an interval of 4 oblique articulations. Example of arm- 

 ramification and proximal syzygies:
