expando-ternates," Bow., fig. 3, Kent., fig. 7a, and the 

 " recurvo-ternates," Kent, figs. 8, 9, are altogether 

 absent in Normania, where their place is taken by 

 the "large subfusiformi-acerates " and the "small 

 subfiisiformi-acerates," Bow., 'Brit. Spong.,' iii, PI. 

 LXXXI, figs. 4 and 9, and the peculiar "abnormal 

 forms of connecting spicula," figs. 6, 7, 8. Indeed the 

 only point in which the two sponges agree is that both 

 are famished with " stellates."

 found by Mr. Carter at Straight Point, Budleigh- 

 Salterton, and described by him in the 'Annals ' under 

 the name Stelletta aspera, is Bowerbank's Ecionemia 

 ponderosa, Mr. Carter's figures of the spicula very 

 closely resemble those of the last-named species, and 

 the fact that he did not find the small doliolate spicula 

 is of little moment, as they might have easily escaped 

 him. In Ucionemia compressa the doliolate spicula 

 were not recorded in the description in Vol. II, and
