72 NOTES ON TASMANIAN CRUSTACEA, ETC. 



the fourth, which is the longest, the fifth being rather shorter ; 

 all the joints are furnished with clusters of short, acute spines ; 

 the side-plate of the first pair resembles those of the gnatho- 

 pods ; that of the second pair is broad and excavate in front ; 

 the third is two-lobed, the posterior lobe being the largest and 

 having five or six short marginal spines. 



The first and second uropods (fig. 11) reach almost as far 

 back as the extremity of the third pair ; the last has the outer 

 branch well developed, but shorter than is usual in the genus ; 

 the inner branch (fig. 12) is represented by a minute lobe 

 tipped with a single seta ; the telson (fig. 13) is cleft half-way 

 to the base, each division ending in four short spines.

 Ser. 5, vol. yi., p. 5, pi. i., fig. 5.) 



Some small specimens of this species were collected by Mr. 

 H. M. Laing in shallow pools between tide-marks on the Huon 

 river. They agree very closely with specimens from New 

 Zealand. 



This species agrees with Boeck's definition of Mcera, except 

 in regard to the second gnathopoda, which have not the hand 

 " much larger than in the first pair." It is somewhat larger, 

 but not more than half as long again, the breadth in both being 

 about the same. 



The species has been found abundantly on the east coast of 

 New Zealand (South Island) by both Mr. Chilton and myself. 



Addendum. 



In Budde- Lund's Crustacea Isopoda Terrestria, p. 285, a 

 species of Armadillo is described from Tasmania, unfortunately, 

 without figures. I append here a translation of his description. 

 The species belongs to the section of the genus, characterised 

 by him as follows : — 



"External terminal rami of the anal feet obliquely tetragonal 

 (trapezoidal), usually much smaller and shorter than the basal 

 articulation, rarely equal in size ; epimera of the first segment 

 of the body simple, slender ; anal segment of the abdomen 

 triangular, with the apex more or less acute." 



Armadillo misellus. 



Oblong-oval, very convex, opaque (?) ; body everywhere 

 distinctly tubercled ; the whole surface minutely pubescent. 



External antennss rather shorter than half the body ; 

 flagellum 5-articulate, shorter than the peduncle ; first articu- 

 lation of the flagellum rather shorter than the next three.
