(B) Animals. 



(1) Phylum Porifera 



Six species of sponges have been examined, one calcareous, Aphrocallistes 

 whiteavesianus, and five non-calcareous. Single specimens were examined in each 

 case. 



(2) Phylum Coelenterata 



The specimens of Obelia were attached to the wharf at the Station. They 

 were washed free from dirt, and preserved in alcohol. Foreign organisms present 

 (diatoms, ostracods, caprellae) certainly did not amount to one per cent, of the 

 total weight. A number of Aequorea were obtained in False Narrows. The 

 Aurelia were obtained in the same region. The sea-anemones were obtained on 

 rocks at Jesse I. The complete organism was not obtainable, but the larger part 

 was removed by cutting as the organisms hung above low water. The comb- 

 jellies, probably a species of Pleurobrachia, were obtained near the Station. These 

 four species were preserved in dilute formaldehyde. Their weights, after hardening
