 of Eden, and a careful examination of this area is sure to disclose further 

 species. 



QUEEXSLAXI*. 



October, 1912, Kedrou Bi-ook. — Specimens had already been received 

 from this source from Dr. Bancroft, but one of the writers [E.H.P.] was 

 anxious to visit this promising locality, which is fast being spoilt by settle- 

 ment. At the time of this visit, which was made from Eagle Junction, 

 there was still some of the original scrub and some giant trees on the river 

 banks. Tamboarlniana vari((hilu, sp. nov., vsiV. flavomacuJ ata , was common, 

 and two species of Arhanitis, A. similarl>i, sp. nov., and A. hirsiitii)', sp. 

 nov., occurred less frequently — all three species being mingled, and all 

 within i-each of flood waters. 



October, 1912. — The basaltic tableland of Tambom-ine Mountain is 

 a typical vine scrub with a dense forest association of palms, Eucalypts 

 and Indo-Malayan trees, e.g., Flindersia, Castaueotipennuiii, DrepIiaiuoKh-a, 

 Cedrela, etc. The trees are of enormoiis height, closely packed together, 

 with long, straight, bare trunks, often branchless, except at the crown, 

 and some forms, nettles, bean trees, and figs, are buttressed up to ten 

 and twelve feet from the ground. The crowns of the Araucaria ciinniucj- 

 liami are laden with epiphytic ferns, which ultimately, by their accum- 

 ulated weight, break the branches and fall to the ground, where they 

 form a suitable nidus for some Territellaria^ Epiphytic orchids and 

 ferns also occupy the trunks, but these were searched in vain for any 

 arboreal form of trap-door spider. 



One of the chief characteristics of the forest is the enormous number 

 of vines, Bignouias, etc., which ai'e seen going up out of sight to reach the 

 sun on the tree tops. There is very little grass or other undergrowth in 

 the denser parts of the forest. On such a high, undisturbed island 

 plateau, we expected to find a rich hunting ground for Araneidiv, and in- 

 deed for Araneida3 as a whole, it is so, being especially rich in Attidsi'. 



The first Territellarian, which presented itself was Atrax callda, sp. 

 nov. (PI. xviii., fig. 29), a near relative of A. versuta, Rainb. This buikls 

 a white funnel of web around the opening of the burrow ; it is abundant, 

 and a large fallen epiphytic fern mass will often contain sevei-al nests. 

 They are common at the old mill, and on digging one out it was found 

 consuming a small frog (llijla), of which, only the two hind legs were 

 left ; whether this is a common habit of the species we cannot say. Like 

 others of the genus Atra.i', this species is of a vicious disposition, and puts 

 up a strong tight before it can be induced to enter a collecting tube. 



Out in the open, chiefly at the base of MacrozKDiia deiiniso)ii, which here 

 reaches a great size, are found the dwellings of the beautiful Arhauitis 

 pulchra, sp. nov. Their peculiarity is the large circular collar of Aveb lying 

 on the ground, spun very close and ap])arently intended to prevent (he 

 dry earth falling into the buri'ow, rathei- than for the purpose of a snare. 

 This species avoids the dense forest. Anotlier species, Arlnoiifis papilio- 

 ftii/t, sp. nov., does not shew any peculiarity in its dwelling. 



At the top of the St. Bernard Falls, looking towards the sea, was 

 found a colony of the large form of Tamhouriniaim variabilis, sp. nov.
