flagellated clianihcrs, but most efficient for the vitally Imporfant 

 function of keeping open the meshes of the dermal network : 



(2) 'Ihat the geometrical forms of cubes, squares, or lines 

 (hexactins, staiiractins, anijiliidisks) arise in correspondence 

 with the requirenients for supporting cubical spaces, surfaces, 

 or concentric laminaj: 



(15) That the support of flagellated chambers and of the 

 botly as a whole was a later need, and was offoctfd by the 

 development of microsclercs into parenchymal and auxiliary 

 surface macroscleres : 



(4) That the identity of axes of the regular hexactin 

 uith those of the regular crystalline system is a coincidence, 

 the real determining factor of the shajie being a biological 

 one : the axes of a geometrical system are pure abstractions. 

 The concrete organic filament of the regular hexactin round 

 which alternating layers of spiculin and silex are formed 

 is nothing more tlian a model of those abstractions. (It is not 

 implied, however, that the cylindrical shape of the axial tubes 

 is to be regarded as an argument against the crystal theory; 

 for crystals may have curved surfaces.)

Ilyalopeplus clavaiiis, sp. n. 



Head, pronotum, scutellum, and corium bronzy ochrnccous ; 

 head with three longitudinal black lines, the lateral ones 

 converging anteriorly ; antennoG with the basal joint bronzy 

 ochraceous, with a more or less distinct piceous line beneath, 

 second joint black, with its base ochraceous (remaining joints 

 mutilated in typical specimens) ; pronotal collar with the 

 margins and three longitudinal lines black, the central line 

 more prominent, posterior pronotal margin and the posterior 

 angles black ; clavus with the inner and outer margins and 

 the suture black ; corium with the costal marginal area paler 

 and bordered on each side with black, veins piceous ; mcm- 



scaffolclings. He resorts to the method of .^jilicing with rope his radial 

 and taugeulial axes (standards, putlogs, and ledgers), because, w hen sepa- 

 rated, they are easier to trant^port in bundles.
