which they were described — are obviously so closely related that 

 they might be ranked as varieties of a single species. The second 

 and third mentioned, however, according to their descriptions, 

 are lacking in the smaller chelae found in the others; if this be 

 so, one might regard these two as varieties of one species, P. 

 moluccensis, and the remaining three as varieties of a second 

 species, P. penicillium. 



Subfamilia Ectyonin^e. 



With the exception of Lissodendoryx jacksoniana, described 

 below, all the species which I have so far succeeded in identifying 

 of the Ectyoninae described in the Catalogue have already been 

 dealt with, at least sufficiently to render possible their identifica- 

 tion, in my former paper. The fuller treatment of such of them 

 as require further description, I propose to defer until a suitable 

 opportunity offers itself of my undertaking a general revision of 

 the Australian Besmacidonidce. 



It is necessary here to refer, however, to certain alterations 

 which a knowledge of additional facts has led me to consider 

 advisable in the conclusions I expressed regarding the four species, 

 Echinonema levis, E. rubra, Clathria macropora, and C. australis. 

 As already stated, the specimens labelled as the types* of the first- 

 mentioned three (as also the specimens representing them in the 

 British Museum) are examples of a single variety of Crella incrus- 

 tans, while those of the fourth species belong to another variety of 

 the same— the variety arenacea Carter ; and thus, although corres- 

 ponding exactly — except (in one important particular) those of 

 Clathria macropora — with the descriptions of the species they 

 respectively purport to represent as regards external features, 

 they are all rather considerably at variance therewith in the mat- 

 ter of spiculation. Nevertheless, except in the case of Clathria 

 australis (which is described as possessing only scarce acantho- 

 styles) the latter discrepancies are such as might conceivably be 



*They are labelled as the types by Mr. Whitelegge. Their original 

 labels in Lendenfeld's handwriting bear only the iM8. names ''Clathria 

 levis," ''Clathria rubra," "Clathria macropora," and "Clathria Jlabellum" 

 respectively.
