The largest of the specimens in hånd measures 8 cm in length, 
corresponding thus very well to the estimate of the size of the 
living animal given byDendy & Hindle. (The specimen is pre- 
served in a very well extended State.) 
To the very careful description given by Dendy & Hindle 
I have only little to add. An important faet is that the tentacles 
contain, almost constantly, calcareous spicules^) of the usual form 
Fig. 63.b; only in two specimens I was unable to find any; in 
some specimens they are fairly numerous. — In the preserved 
specimens the posterior end rather commonly is found to be some- 
what swollen and the cloaca evaginated, which makes these spe¬ 
cimens look rather peculiar, Edwardsici-WVit. The ciliated funnels 
may be very scarse or even wanting along the mesentery. Dendy 
& Hindle State them to oceur also on the longitudinal muscle- 
bands, without stating more exaetly on which of them. I have 
found them to oceur along the right side of the mid-ventral and 
along the upper side of the left latero-ventral muscle. There is a 
distinet retractor part of the usual shape, the elevated part of the 
muscle beginning at about a centimeter’s distance from the anterior 
end. The eggs are small, ca. O.i mm, which may indicate that 
this species has a true pelagic larva. — Two of the specimens 
from Plimmerton are infested with an ectoparasitic snail. 
The new localities given here, together with those given by 
1) This faet has some practical importance, the existence of spicules in the 
tentacles giving definite proof that the absence of spicules in the body 
Wall of such specimens is not due to the preserving fluid having been 
acid and thus caused their disappearance.
