. The naturalist in Australia. Natural history. 216 THE NATURALIST IN TT. Saville-Kenf, Photo. As matters stand, this rock may conveniently serve as a guide-post to that particular spot in the Bay, whence, when the tide was low, a con- siderable number of the marine forms illustrated or referred to in these pages were collected or ob- served. Although so high up within the tropics, the reefs of Roebuck Bay, which render navigation to the port of Broome extremely intricate, are not of coral, but are stratified replicas of the much-inter- rupted friable red sand-stone cliffs that line the shore. Coral grows here, but very sparingly compared with a little farther to the north and east. In place of it, certain other marine organisms are abundant to an extent that has not been observed by the writer on any other part of the Australian coast-line. The zoological group most in evidence among the reefs at low tide, at what is known as Entrance Point, close to the " Rhinoceros Rock " of our Chapter heading, is that of the Ascidians. One particular type, referable to the genus Colella, literally festoons every ledge and crevice of the much-eroded rocks in such a manner that their aspect, as seen from a little distance, presents a remarkable resemblance to stalactitic formations. The luxuriant growth of these Colellse, together with the peculiar petrological resemblance suggested, will be recognised on a reference to the accompanying corner illustration, which is composed of the joined-up replicas of several photographs that were taken of contiguous areas. In the lowermost section the Ascidians are taken from a nearer point of view, and being more considerably.
