Bate writes: ‘Cape York; north of New Guinea; North-west 
Pacific.” In the collection I found one specimen from Cape York 
labelled “type,” furthermore, one and a half specimen from the 
same locality, all correctly referred to the Kréyerian species. In 
a preparation I found a specimen determined as S. corniculum 
from “N.W. Pacific”; it measures 10°4 mm. in length, but 
according to the shape of the ext. br. of urp., the eyes, &e., it is 
not that species but S. ancylops Kr., the Mastigopus of S. atlanticus. 
From the third locality, ‘north of New Guinea,” no specimen 
could be found.

Bate has two localities: “New Hebrides; Pacific, July 20, 
1875.” I found one specimen from “ New Hebrides” correctly 
referred to the Kréyerian form.—In three other tubes, specimens 
not mentioned in Bate’s text were present; they belonged to 
three other species, but are mutilated and could not be determined.

Bate writes: ‘Mid Atlantic, April 1876,” and according to 
the following line he had one specimen. But in the collection I 
found three tubes, each containing one specimen, all determined 
as S. longirostris, and two of them from ‘ N. Atlantic,” while the 
third had no locality ; all three specimens are the young MZastigopus 
of S. corniculum Kr., H. J. H. The specimen without locality 
seems to be the type for Bate’s figure of S. longirostris, but it 
measures scarcely 3mm. in length, the rostrum not included, and 
in Bate’s figure the eye-stalks are too long, the eyes too small, and 
the third joint of the antenn. ped. too short (it is in reality as 
long as the second). 
SERG. JUNCEUS Bate, p. 416, pl. lxxvi. fig. 1. 
According to the text Bate has seen one small specimen from 
the “South Pacific Ocean.” It could not be detected in the 
collection. But in my earlier paper I pointed out that it must 
be the young Mastigopus of S. tenwiremis Ky., H. J. H. 
SERG. LONGISPINUS Bate, p. 417, pl. lxxvi. fig. 2. 
Bate has two localities: ‘Station 106... Mid Atlantic”... 
and “Station 354.... North Atlantic Ocean.” The collection 
contained two specimens referred to this species and labelled 
“93 Aug. 1873, 70 meters ”; in the text we find “Station 106, 
August 25, 1873; lat. 1° AT’ N., long. 24° 26’ W.; Mid Atlantic 
Ocean”; but in spite of the small difference as to the date 
(probably originating from a misscript) I am sure that one of 
the two specimens was captured at Stat. 106. The other 
specimen is probably from Stat. 354. Bate writes: “the specimen 
from the tropical part of the Atlantic” and “that from the North 
Atlantic,” which indicates that he had only one specimen from
