Differs from Amphiblestrum : 1st, in the avicularia being 

 situated in distinct and separate cells from the zocccia (in the 

 type species they vary greatly in size : the larger arc long, 

 ovate, contracted near the middle in the position of the 

 complete but easily broken bar; in the smaller the anterior 

 portion is loop-shaped and the posterior a mere slit) ; 2nd, 

 in the absence of pore-chambers (at any rate, I have not 

 succeeded in seeing any) ; 3rd, in the remarkable character 

 of the distal end of the zooecium, which is divided into 

 chambers by a transverse and usually one or two vertical 

 connecting-bars. These chambers most probably are in con- 

 nexion with the ooecium, which is well raised, globose, and 

 situated over the chamber just described. There are two or 

 three pair of spines, the lower pair forked at their extremity. 

 I illustrate the ooecium, which has not hitherto been figured. 



Specimens of this species from 100 fathoms off Shetland, 

 and from the Hardanger Fiord, Norway, are in my collection.

Zocecia triangular or subtriangular, but very irregular in 

 form. Calcareous portion of the area similar to that of Am- 



* \apva^, a chest or coffer, in allusion to the structure of th(> anterior 

 part of the zoosciuui. 



t (ivrpov, a cave or hollow, with reference to the hollow in wliich tlie 

 oral opening lies.
