REPORT 



ON THE 



CALCAEEOUS SPONGES 



COLLECTED BY 



ME. JAMES HORNELL 



AT 



OKHAMANDAL IN KATTIAWAR IN 1905-6. 



BY 



ARTHUR DENDY, D.Sc, F.R.S., 



Professor of Zoology in the University of London (King's College). 



[With Two Plates.] 



The collection of sponges from Okhamandal placed in my hands by Mr. James 

 Hornell contains six species of Calcarea, unfortunately not in a very good state of 

 preservation. I have found it necessary to describe as new one species of Sycon {S. 

 grantioides) and one of Leucandra {L. dwarkaensis), together with a variety of Leucandra 

 donnani (var. ienwi/radiata). More interesting than these new forms, however, are the 

 specimens of Grantessa hastifera (Row) and Heteropia, 'glomerosa (Bowerbank), which 

 enable me to add a good deal to our knowledge of these little known species. 



The classification adopted is that of Dendy and Row's [1913] "Classification and 

 Phylogeny of the Calcareous Sponges, with a Reference List of all the described Species, 

 systematically arranged." I have followed my usual practice of quoting the Register 

 Number (R.N.) of each specimen in order to facihtate accurate reference. 



1. Sycon grantioides, n. sp.— (Plate I, Fig. i.) 



The single specimen, unfortunately in a bad state of preservation, has the form 

 of a slightly compressed cylinder, rather wider above than below, but contracting
