of the length, and that the central capsule is about three-fourths as 

 broad as long. The statoblast has thus neither the attenuated 

 outline of that of P. philippinensis nor the broadly oval form of 

 that of the typical P. repens. The form mighty therefore , so far as 

 the proportions of the statoblasts are concerned, fall into either 

 of Kraepelin's two species P. polymorpha and P. princeps, which 

 represent respectively the group related, as regards this character, 

 to P. repens and that related to P. emarginaia in the same way.

Lophopus carteri (Hyatt). 



Zoaria consisting of small, mound-shaped, colourless masses o. 

 gelatinous consistency, which have the power of progression 

 without any specialization of the base and are capable of 

 coalescing by means of their gelatinous investment to form 

 compound colonies of a temporary nature. Zooecia tubular, 

 upright, rather short ; their walls consisting of an inner cellular 

 layer and an outer gelatinous one devoid of cells in the living 

 organism. Stomach yellow, rounded, but not broadly, at the 

 base; lophophore bearing about sixty tentacles, which are 

 distinctly webbed at their point of origin. Statoblasts (fig. 3) 

 large, somewhat variable in size and proportions, but averaging 

 about 0*85 mm. by o"56 mm., truncately oval in outline, 

 curved longitudinally, with a wide swim-ring and an almost 

 circular capsule, which is relatively small; the statoblast bear- 

 ing at each end a series of straight processes, each of which is 

 armed with a row of minute, blunt hooks on either side. . 



This form only differs from my L. himalayanus in the larger 

 number of tentacles borne by its lophophore, and in the more 

 perfect development of the processes on the statoblasts. In 

 L. himalayanus these are sometimes reduced to minute rudi- 

 ments (fig. 4) in statoblasts proved by their dark colour and by 

 the fact that they are found floating free in large numbers, to be
