TWO NEW VICTORIAN SYMPHYLA OF THE GENUS HANSENIELLA 1 
secondary whorl begins on the lower side of the seventh or eighth segment, 
first appears dorsally on about the fifteenth, and is well developed by about 
the twenty-first or twenty-second. A third whorl begins, on the lower side, 
on about the seventeenth segment. On the more distal segments the 
individuality of the whorls tends to become more obscure (cf. Fig. 1a). 
Except for an occasional diminutive seta, the setae of the whorls are 
approximately equal in length, measuring about three-fifths the thickness 
of the basal antennal segments. Terminal segment provided with three 
stalked sense-organs (“striped organs”), of which two are small, the third 
nearly twice as large, and with a broad base (Fig. 1b). The large sense-organ 
seems, on close examination, to consist of a central spine surrounded by 
a ring of six lesser spines. In addition to these sense-organs on the terminal 
segment, there is a sense-organ of similar type on each segment from the 
third onwards. Under high magnification it is seen to consist of a long 
central spine surrounded by a ring of four lesser spines (Fig. Ic). 
Comparable organs have been described by Imms (5) from H. (Scutigerella) 
subunguiculata. 
Scutes . — The first two scutes convex on their posterior margin; from 
the sixth backwards they are gently indented. On each scute except the 
fourth, seventh, tenth and fourteenth, a single pair of very enlarged 
outwardly directed lateral setae. The enlarged setae of the first scute nearly 
three times the breadth of the basal antennal joints. Following Hansen, I 
have reckoned the scute of the second leg-bearing segment as the first, 
the diminutive scute of the first segment being customarily excluded from 
the series. It is devoid of a large lateral seta. 
Legs . — On the last leg the tarsus is five times longer than thick. 
“Metatarsus” and tarsus each with eight setae in the outer dorsal row. On 
the “metatarsus” the most distal seta is the largest; it measures more 
than half the thickness of the “metatarsus.” The anterior claw (Fig. Id) 
of the last leg is slightly curved, and forms at its base a broad blade which 
tapers sharply one-third the length of the claw from its basal end.^ The 
posterior claw more curved, being two-thirds the length of the other. “Front 
seta” unusually long, being nearly as long as the anterior claw; its basal half 
broad and blade-like, its distal half tapering into a thin filament. 
On the first leg the anterior claw (Fig. 1e) is rather less curved than 
on the last leg, and the basal blade-like portion is less pronounced. Posterior 
claw curved and about half the length of the anterior claw; basal portion 
unusually sharply demarcated. “Front seta” robust and a little longer than 
the posterior claw. 
Cerci. (Fig.lr). Their length from four to five times their thickness. 
Clothed with numerous relatively small setae, of about equal size, except that 
they enlarge a little towards the apex. At the apex itself is a single enlarged 
seta, a little longer than the thickness of the cercus at its base. 
Habitat.— Belgrave, Marysville, and Otway Range, Victoria. The animals 
occur under stones and in decaying vegetation ; well-decayed trunks of tree- 
ferns (Alsophila, Dicksonia) are especially favourite haunts, and they can 
usually be obtained in numbers by breaking up the rotting stems. A moist 
but not wet environment is always selected. 
Type in National Museum, Melbourne. 
Of the described species of Hanseniella the present species 
seems to resemble most closely, though it is clearly not 
identical with, a foirni described by Archey (1) from New
