pp. 1289-1291. 
Bateson (115) describes a structure which he regards as comparable 
with the notochord of the Chordata , and points out the resemblances 
between the central nervous system of Balanoglossus and Amphioxus. 
B. hachsi (Yokohama) and B. talaboti (Marseilles), spp. nn., Marion 
(116). 
The species exhibited by Bell (P. Z. S. 1885, p. 836), from Herm, has 
since been described by Koehler from the same locality.

Nansen (117) has studied My zo stoma cirriferum, M. glubrum , M.gigas , 
M. carpenteri ; and 21. giganteum , and 21. graft, spp. nn. (from Antedon 
celtica , pp. 5, 6, & 69). He does not regard the Myzostomida as be¬ 
longing to the Chcetopoda , but as a distinct group of Annelids, related to 
Chtetopods, but with a tendency to some of the Arachnids and Crusta¬ 
ceans.
