with which (or the main excurrent canals dervied therefrom) they commu- 

 nicate by a more or less complicated excurrent canal system. The skeleton 

 of the Chamber layer is largely composed of irregularly scattered radiate 

 spicules, but it always has regularly placed subgastral chiactines. Diese 

 Diagnose weicht von der von Dendy für Leucandra durch das Vorhandensein 

 regulär angeordneter subgastraler Chiaktine ab. Hierher M. cruciferua

Staurorrhaphidae n. fam. There is a distinct and continuous dermal cortex, 

 completely covering over the Chamber layer and pierced by inhalent pores. 

 There are no subdermal sagittal triradiates nor conspicuous subdermal 

 quadriradiates. The flagellated Chambers vary from elongated and radially 

 arranged to spherical and irregularly scattered ones, while the skeleton 

 of the Chamber layer varies from regularly articulate to irregularly scattered, 

 but there are always regularly disposed subgastral chiactines. Diese Diagnose 

 differiert von Dendys Definition für die Grantiidae nur durch das Vor- 

 handensein regulär angeordneter Chiaktine in der Subgastralregion. Hierher

Streptoconus n. g. Chiphorids in which the radial Chambers are usuaUy more 

 or less united at places where they come in contact with one another, and 

 are always crowned at the distal extremity with tufts of oxeote spicules. The 

 tubar skeleton is articulate, the first Joint being formed of chiactines. Str.

Merlinae n. subfam. der Pharetronidae, in which the solid skeletal framework 

 is constructed of vertical main beams of fibrillar cement, from each of which 

 there radiate three vertical flanges to meet similar flanges from other co- 

 lumns so as to form cylindrical tubes; the latter are partitioned off by hori- 

 zontal floors, a honeycomblike structure resulting. Solid framework without
