BRYOZOA OF THE CAPE VERDE ISLANDS.

pyriform, to some of which there is a tube without any funnel, but other 

 ovicells show no tube. In the British Museum specimens there is a slight 

 funnel. The aperture of the ovicell tube is about 0'08 mm. There is usually 

 a branch on each side near the base of the ovicell. The bases rami are long — 

 that is, they reach to the next zooecium below. 



This is much like C.pacifica*, Robertson ; but from Dr. Alice Robertson's 

 ficrare the distance from zoaecium to zooecium is onlv about 0'33 mm., so that 

 it is a more slender species than tubulosa. Busk. C. pacified, Rob., C. maxima, 

 Rob., C. pugeti, Rob., all seem closely allied.

There are several colonies from the Cape Verde Islands which are about 



12 mm. long, forming close tufts much less straggly than is usually the case
