CRUSTACEA. 



Length, four lines ; breadth, half the length. The so-called spinules 

 are not acute, and might perhaps be more properly called setules. 

 The processes on the head below the eyes are not in view, unless the 

 head is placed out horizontally, as it would be carried by the animal 

 when walking. The epistome is spinulous like the back. The 

 caudal lamellae have a small joint at the extremity, as described by 

 Krauss in his South African species (Siidaf. Crust., p. 63, pi. 4, f. 5, 

 6) ; and as he suggests, there are differences between the specimens 

 and the figures of Savigny's species, in this and other respects, which 

 may require the institution of a new genus. The animal rolls up 

 into a ball, like the Spheromse. 



Subfamily II. ARMADILLINiE. 



Armadillo speciosus. 



Corpus valde convexum, subtiliter granulosum. Caput anticd fere trurir 

 catum. Segrnenta thoracis lateraliter non acuta, anticum majus. 

 Abdominis segrnenta strict^ conjuncta, idtimum apice arcuatum et 

 valde latins, lateribus excavatis. Appendices caudales angustw, ad 

 apicem truncatw, marginibus parallelis integris et nudis. Antennce 

 tenues, flagello plane breviore quam articulus quintus. 



Body much convex, finely granulate. Head nearly truncate in front. 

 Segments of thorax laterally not acute, anterior largest. Segments 

 of abdomen with their margins closely in contact throughout, the 

 last much broadest at apex, and with the sides excavate. Caudal 

 appendages narrow, apex truncate, margins entire, nearly parallel, 

 naked, basal portion rectangular, produced inward. Antennae 

 slender, flagellum distinctly shorter than fifth joint. 



Plate 47, fig. 2 a, animal, natural size; b, under view of abdomen; 

 c, caudal stylets, separated and much enlarged; d, antenna, much 

 enlarged. 



From moist soil, among leaves, in the crater of Taiammai, New 

 Zealand, in the vicinity of the Bay of Islands. Collected, March, 1840.
