LOXOSOMA LOXALINA AND LOXOSOMA SALTANS. 137 
on L. crassicauda, and shown by Pronho on L. annelidi- 
cola. On the four larg-e oral tentacles there is a little tuft 
of hair on tlie tip of each on its outer border as shown in 
fig. 10. These are the ones which seem to aid in locomotion. 
Budding. — I have had so few specimens that I have been 
unable to study the development of buds. In no case did I 
find more tlian two buds ; nor were these buds very lai ge. 
It would be rash to say that two buds is the limit of the 
number borne at once by an individual, seeing that in other 
forms so many may be carried at the same time. On the 
other hand, it is not improbable that two should be the limit 
in this species, for, as one may well imagine, a little species 
like this which is capable of such active locomotion might 
not find it advantageous to be encumbered by more than a 
couple of buds at a time. 
The only other Loxosoma that I have found in Scotland is 
L. phascolosomatumin the Kyles of Bute. 
Two new species of Loxosoma have recentl}^ been described 
by Nilus in the ‘Trav. nat. C.R. seances St, Petersburg,’ vol. 
xl, and named L. mur manica and L. B rumpti respectively 
These are very unlike the two species described in the above, 
and resemble L. tethyae more closely, having a small cir- 
cular lophophore with only six tentacles, with no very evident 
epidermic gland-organs, and with many buds arising low 
down on the body-wall. 
Summary. 
(1) Loxosoma loxalina n.s. — Lophophore larger than 
the body and bears sixteen tentacles, of which four are longer 
than the others. These four are on the oral part of the 
lophophore, which is slightly inflected along that region. 
T he stalk is considerably longer than the calyx, and tertninates 
in a circular foot with radiating supporting cells. There is 
no foot-gland. The body and the lophophore are beset with 
deeply placed ectodermal organs along the lateral margins.
