Ol>s. This sponge has been named, described, and illus- 

 trated by Dr. Bowerbank, as above indicated, from '' Shetland, 

 in the cabinet of the Kcv. A. M. Norman ;" but as the speci- 

 mens were dry and mine is wet, it has seemed to me desirable 

 to describe and figure it again from the latter. The ligures on 

 the jar are " G7 and 08," which give the locality and depths 

 above mentioned. On one of the cones has grown a specimen 

 of Grant ia ciliata^ *? var. (tig. G), and a small one of TetJn/a 

 cranium (fig. 5, a). This is all that is in the jar. The 

 Grantia will be described hereafter. 



In the British Museum, among the specimens dredged up 

 on board the ' Noma ' on the coast of Portugal, is a sponge 

 of a similar conical form, also grouped, but with a tuberculated 

 surface, each tubercle of which is supported on a bundle of 

 spicules that radiate from a solid, conical, central axis. 

 Here, however, there is only one kind of s])icule, viz. acuate, 

 smooth, and sharp-j)oinled ; so that it does not belong to the 

 Ectyonida, but, belonging to the Axiuellida, might be called 

 '^ Ciocah/pta (Bk.) tuberculata^^^ seeing that, like other species 

 of this group about to be mentioned, it will probably have to 

 come under the order Echinonemata. 



Another similar (/. e. conical) form has been described and 

 named by Dr. Bowerbank Ciocalypta pe}ii'cillus (Mon. Brit. 

 Spong. vol. ii. p. 81, and vol. iii. pi. xiii. figs. 2-4) ; but this 

 is a massive one, in which the characteristic conical lieads, at 

 first grouped, soon })ass into a common body from which the 

 characteristic ends alone project. There is a s[)ecimen of this 

 kind in the British ^luseum, G inches in diameter, wdiich, from 

 its white surface and yellowish interior, might be taken for 

 J la/ who udria pnniceay J ohnst. It also has oidy one form of 

 sj)icule, viz. acuate, smooth, sharp-pointed. 



A third species has been named ''C. Ztci " by Dr. Bower- 

 bank {oj). cit. vol. iii. pi. Ixxxvi. figs. 1-3) ; it, again, has 

 only one form of spicule, viz. acuate.
