CALCAREOUS SPONGES. 763 



South-Western Australian Expedition of 1905. As neither 

 Mr. Carter's Hypograntia nor the species H. infrequens were 

 ever recognisably diagnosed, we do not consider it necessary to 

 abandon the generic name Gi-antiopsis. The question will be 

 more fully dealt with in the forthcoming report on the above- 

 mentioned collection [Row 1913 MS.]. 



We recognise the following species in this genus : — 



1. G. CYLmDRiCA Bendy. Type species of the genus. 



Grantiopsis cylindrica Dendy [1892 B]. 



2. G. INFREQUENS Carter. 



Hypograntia infrequens Carter [1885-1886]. 

 Grantiopsis infrequens Row [1913 MS.]. 



Genus 26. Sycute nov. 



Diagnosis. Canal system sj^conoid. Dermal cortex provided with 

 colossal longitudinally arranged oxea. Tubar skeleton 

 articulate. Distal ends of the flagellate chambei's crowned 

 with tufts of oxea lying between the colossal longitudinal 

 oxea. 



For illustrations of this genus see Kirk [1894]. 



This genus has been provided for Kirk's Sycon dendyi, a species 

 which is curiously inteinnediate in character between Sycon and 

 Ute, retaining the well-defined tufts of oxea which are charac- 

 tei'istic of Sycon and at the same time possessing the colossal 

 longitudinal oxea characteristic of Ute. 



The only known species is : — 



1 S. DENDYI Kirk. 



Sycon dendyi Kirk [1894]. 



Genus 27. Ute O. Schmidt [1862] (emend.). 



Diagnosis. Canal system syconoid. Tubar skeleton articulate. 

 Dermal cortex well developed, containing colossal longi- 

 tudinal oxea. No tufts of oxea at the distal ends of the 

 flagellate chambers. 



For illustrations of this genus see Dendy [1893 A]. 

 We allocate the following species to this genus : — 

 Section A. Without microxea. 



1. U. ENSATA Bowerhanh. 



Qrantia ensata Bowerbank [1864-1882]. 

 Sycandra glabra var. ensata Haeckel [1872].
