Appendicularia Mossi, Herdman, 1888. 
Mossia dolioloides, Herdman, 1891. 
Tail 5% times as long as the body. 
Caudal muscle-bands three times as wide as the dia- 
meter of the notochord. 
Intestine (apparently) of normal length; anus situated 
on a papilla. | 
Habits —When at rest, the tail is rolled upon itself 
in a characteristic scroll-like manner. Not known 
to forma lelaus. | 
Distribution.—Found in 1867-1868 in the warm 
surface-water of the Atlantic, near the Equator, 
and occasionally so far north as off the coast of 
Portugal. 
DESCRIPTION OF PLATE V. 
1. Kowalevskia Mossi, Herdman. An exact copy 
of Moss’s figure (Trans. Linn. Soc., vol. xxvu, Pl. 
47, fig. 5), of which the following is the original 
explanation :—A, vascular canal of the appendix. 
B, muscular bands of the appendix. C, nervous cords 
of the appendix. D, central axis [notochord] of the 
appendix. G, branchial orifice. I, nervous branches 
surrounding the branchial orifice. K, otolithe and 
its sac. M, principal nervous trunk. Q, rectum. 
R, stomach [? intestine]. 8, ovary. 
In repeating Moss’s explanation, I ought to add that 
this observer was undoubtedly wrong in attributing 
two nerve-cords to the tail of this Appendicularian. 
He made the same mistake with regard to Otkopleura 
and Pritullaria.
