tulates, relatively magnified. Scale l-48th to 1 -6000th of an 

 inch. 



Fig. 9. The same, pore surrounded by ovoid cells, seen through the cuti- 

 cula : a, ovoid cells ; b, epithelial cells lining the pore. Scale 

 l-24th to l-6000th of an inch. 



Fig. 10. Chondrilla australiensis, n. sp., small specimen attached to a 

 piece of oyster-shell : a, Chondrilla ; b, oyster-shell ; e, vent : 

 magnified 2 diameters. 



Fig. 11. The same, vertical section, nat. size. 



Fig. 12. The same, vertical section (No. 11) magnified 8 diameters: 

 a, cortical translucent rind ; b, body-substance, opaque; c, oyster- 

 shell ; d, pore-tubes passing down vertically through rind ; 

 e, pore-tubes, enlarged, branching and apparently opening direct 

 into excretoiy canal -system ; f, excretory canal-system, segmented 

 in the section ; g, vent, or single termination of the same ; h, 

 sph aero-stellate and radio-stellate spicules imbedded in the cortex. 

 The spicules, though really existing throughout the mass, are 

 generally not inserted, for the sake of perspicuity, any more than 

 the ovoid cells and opaque structure of the body-mass. 



Fig. 13. The same, portion of the surface, showing pore-openings, ver- 

 tical view : a, pore ; b, surrounding granules. Scale l-48tu to 

 l-0000th of an inch. 



Fig. 14. The same, portion of the body-substance, showing : — a, trama, 

 consisting i ffine fibrillae or filaments and minute granuliferous 

 cellulse ; b' ovoid cells lined with cellulse, situated in ovoid 

 cavities of the trama ; c, sphsero-stellate spicules. All relatively 

 magnified ; scale l-48th to l-6000th of an inch. (Compare 

 with fig. 8, on the same scale, to show that the cells of Corticium 

 are only half the size of those of Chondrilla.) 



Fig. 15. Corticium abyssi, diagram of fragment of excretory canal-system, 

 to show characteristic epithelial-cell lining : a, vent ; b, u frag- 

 ment." (In Chondrilla australiensis this cell lining is not 

 present, probably from defective preservation.) 



Fig. 16. Chondrilla australiensis, spicules of: a, spha?ro-stellate ; b, radio- 

 stellate. Scale l-12th to 1 -6000th of an inch. 



Fig. 17. Rhabdolithes Schmidtii, Cart. Scale l-12thto l-0000th of an 

 inch. (See Schmidt's figures and description, 'Annals,' 1872, 

 vol. x. p. 359, pi. xvii.) 



Fig. 18. Sphcerolithcs abyssi, n. sp., Cart., average largest size. Same 

 scale. (The double line is a deception here; it should merely 

 signify the outer boundary of the layer of cellules, in fact the 

 capsule which is perfectly spherical.) 



III. — A Catalogue of the Neuropterous Insects of New Zea- 

 land ; with Notes, and Descriptions of new Forms. By 

 Robert M'Lachlan, F.L.S. 



It lias been represented to me that the entomologists of New 

 Zealand are greatly in need of classified lists of the insects of 

 that colony, and that any contribution in this way would be 

 welcome. Acting upon this suggestion, I have drawn up a 

 catalogue of the New-Zealand Neuroptera (in the Linnean
