Another species with which the present might also be 

 confounded^ and from which it appears to differ only in 

 the absence of oral spines — is the Escharina cornuta of 

 D'Orbigny {' Voy. a I'Amer. occid./ plate v) .

Hab. Jersey, Mrs. Buckland. 



This large and beautiful species, for which the British 

 Fauna is indebted to Mrs. Buckland, corresponds so closely 

 with Sa^dgny's figure of L. Cecilii, that there can be little 

 doubt of the two being identical.

 Had. New Zealand, Br. Sinclair. 



This curious Sertularian appears to constitute a peculiar 

 type of the family to which it belongs. 



The specimen from which the description and figures were 

 made, collected by Dr. Sinclaii* in New Zealand, and now in the 

 British Museum, is about six inches high, and consists of a 

 single central stem or rachis, Avith alternate branches on either 

 side in the same plane, and which become shorter as they 

 approach the summit. The lower part of the rachis or stem 

 is toothed on each side, the teeth evidently representing the 

 roots of branches which have been broken off. Towards the 

 lower part of the pinnate portion, one or two small branches 

 also simply pinnate may be seen springing from the main 

 stem. 



The stem and branches are composed of small tubes ; and 

 the cells are completely immersed among these tubes ; the 

 mouth even, being depressed below the surface, and present- 

 ing itself in the upper part of an elongated pit, surrounded 

 with a raised border, which arches above the mouth of the 

 cell.
