140 Mr. H. J. Carter on the 



yellow or light grey colour. Fibre thus formed of two kinds 

 — viz. vertical or large, and horizontal or small ; terminating 

 externally in a more or less minutely reticulated even surface. 

 Structure vertical. Texture compact, more or less fragile. 

 Forms massive, lobed. 



Family 3. Pseudohiecinida. 

 Group 17. Pseudoarenosa. 



Sarcode the same as in the foregoing group. Skeleton 

 also composed in the same way, but with the addition of 

 "proper spicules" to the foreign objects. Fibre, structure, 

 texture, and form as in the foregoing. 



Group 18. Chalmohircinina. 



Sarcode ? (absent.) Skeleton composed of a reticulation of 

 horny, anastomosing, transparent fibre of a light or dark amber- 

 colour, cored with a mixture of minute foreign objects and 

 " proper spicules." Fibre of two kinds — viz. vertical or large, 

 and horizontal or small ; the latter chiefly cored with the 

 " proper spicules." Surface? (worn off.) Structure vertical, 

 radiating, or plumose. Texture open, resilient, easily com- 

 pressed. Forms massive, lobed or branched, or flat*. 



Group 19. ArmatoMrcinhia. 



Sarcode? (absent.) Skeleton the same as in the foregoing- 

 group, but with the fibre echinated also with " proper 

 spicules." Fibre, structure, texture, and form the same as in 

 the foregoing. 



RAPHIDONEMATA. 



Family 1. Chalinida. 

 Group 1. Digitata. 



Sarcode pale tawny, pink, or purple throughout. Skeleton 

 composed of a reticulation of anastomosing transparent fibre 

 of a pale yellow colour, more or less cored with " proper 

 spicules." Fibre of two kinds — viz. vertical or large, and 

 horizontal or small ; terminating externally in anastomosis, 

 where it is connected with and covered by a minutely reticu- 



* It is questionable whether the family " Pseudochalinida " (at the 

 end of the Raphidoneniata) should not come in here. If the presence ot 

 foreign objects in the core is to determine this, it should ; if the form, 

 then it should remain where it is.
