of S. arcticus Ky., but having in London no material from the 
North Atlantic of S. rinkit Ka., for direct comparison of minute 
details, and some other species allied to S. areticus being known 
from the Indian Ocean and the Pacific, I could not determine the 
larvee enumerated with absolute certainty. 
One specimen from Cape York, determined as S. rinkii, but 
not mentioned in the Report, is S. corniculum Ky., im a stage a 
little younger than that figured by Bate as the last-named species, 
One specimen, labelled “ 25. 8. 73,” determined as S. rinkit, 
but not mentioned in the Report, measures nearly 7 mm.; it 
belongs to S. penerinkii Bate, the young larva of S. diapontius 
Bate, H. J. H. 
Sere. ocuLatus Kroyer, Bate, p. 406, pl. lxxiv. fig. 1. 
Bate enumerates six localities. From Stat. 106 three specimens 
were obtained, from Stat. 257 one specimen, from Stat. 103 one 
specimen, finally from ‘“ September 12, 1875, South Pacific,” one 
specimen: all six specimens correctly referred to the Kroyerian 
species, which is the Wastigopus of S. edwardsti Kr. (compare my 
earlier paper). From the two remaining localities, viz. ‘“‘ North 
Pacific, near the Sandwich Islands, August 21, 1875,” and 
“ August 27, 1873... off St. Paul’s Rock,” no specimens could 
be discovered. 
Sere. ovatocuLus Bate, p. 408, pl. xxiv. fig. 2. 
Bate gives the locality “The North Atlantic Ocean.” In the 
collection I found three specimens with the label ‘ 14 June, 1873,” 
which agrees with my quotation from the text. These three 
specimens are identical with S. ancylops Ky., which is the 
Mastigopus of S. atlanticus H. Milne-Edw. 
SERG. PARVIDENS Bate, p. 409, pl. xxiv. fig. 3. 
Bate has the. following localities: ‘The tropical part of the 
Atlantic; Pacific Ocean, north of the Sandwich Islands; off 
Sydney and Wellington, Australia.” Just below he writes: 
“Specimens of this species or variety were taken during the 
passage from Teneriffe to St. Thomas”; and in the collection one 
specimen from the last-named locality is present: it belongs to 
S. vigilax Stimpson, the Mastigopus of S. vigilax Stimps., H. J. H.; 
it agrees with Bate’s description and figure, and it had already 
been pointed out by Ortmann and myself that S. parvidens Bate 
belonged to S. vigilaw Stimps. Examples from the other localities 
mentioned by Bate could not be found.—From “ Cape York” two 
specimens determined as S. parvidens were present: one of them 
is a young S. oculatus Ky. (the Mastigopus ot S. edwardsii Kv.); 
the other is allied to S. incertus H. J. H., but is so badly preserved 
that a determination was impossible. In a preparation a small 
specimen from the “ China Sea,” determined as S. parvidens, was 
preserved ; it seems to be S. ocwlatws Ky., but it is in a very bad 
condition.
