cles, 2mm. long, directed backwards and visibly outwards ; on 

 dorsal margins are a series of sigilla, ten in each row (in one 

 specimen eleven are represented in anterior row, the second 

 outer sigillum on left side having a double form, probably- 

 abnormal) ; anterior row — central pair circular, smallest of 

 series ; outer sigillum large, ovate ; between latter and inner 

 sigillum are intermediate forms decreasing in size ; in posterior 

 row outer pairs of sigilla are smaller and of a linear-oval 

 form ; in centre of abdomen are four small linear-oval sigilla 

 representing a trapezoid, whose posterior side is widest ; from 

 the tumid posterior margin abdomen dips abruptly, 4mm., to 

 spinners ; this area has, including the marginal, five well- 

 developed transverse corrugations, first connects base of 

 posterior lateral spines, second projects backwards, and bears 

 the spine-like tubercles ; three corrugations on ventral sur- 

 face ; in all grooves are small sigilla, ten in first row ; at 

 extremity of each wing-like projection is a large, blackish, ovate 

 sigillum, equal to dorsal one in size. Vulva black ; large, 

 somewhat conical, apex rounded ; viewed from posterior end 

 displays a membranous ridge, terminating beyond base. 



This species is closely allied to Gastcracantha, loestringii, 

 from New Holland, described and figured by Koch in " Die 

 Arachniden Australiens." Two examples were captured by 

 Miss Lodge at Norfolk Island. I am indebted to Mr. T. F. 

 Cheeseman, F.L.S., for the specimens which he handed over 

 to me for determination.

The following descriptions include all the material reiuaining 

 undescribed in my hands of these groups. It is for resident 

 collectors to obtain fresh material and information on the 

 habits of described species, and I shall at all tunes welcome 

 any communication from those who have the opportunity of 

 doing so, and will gladly determine any species sent to me.
