Three sponges referable to this species were collected in the Gulf of 

 St. Lawrence. They are massive and somewhat irregular in shape ; one 

 specimen is, roughly, about 55 mm. broad and 20 mm. high ; another is 

 slightly larger, and a third, preserved in alcohol, is about 22 mm. long 

 and 12 mm. high. When dry they are extremely friable. 



There is little difference in the size of the megasclera, but the mic- 

 rosclera vary considerably in shape as well as in size. Oxea ; length 

 from 0-255 to 0-307 mm. (Plate I., fig. 4a). Sigmata ; average width 

 from curve to curve 065 mm. (Plate I., figs. 46, 4c, 4d) ; a smaller 

 form of the ordinary shape and about 0*026 mm. is also present in small 

 numbers. 



Vosmaer has described a vainety of Gellius vagabundus^ (O. S.), with 

 spicules so similar to those of G. flagellifer that Eidle}^ and Dendy think 

 it is "not improbably referable" to their species.^ Yosmaer gives the 

 " Arctic and Atlantic (Florida) " as the geographical distribution of his 

 sponge, so that it would not be very surprising to find it occurring at 

 even such a distant locality as off southern Avistralia.
