The following is the description of a male which probably pertains 

 to the above species : — 



Maris : — Pedes Mi et sequentes ac supra. Antennae inferiores paulo 

 longiores, articulis flagelli valde oblongis. Antennae superiores climidio 

 basis inferwrum paulo longiores, fiagello Q-articulato. Pedes Imi 

 manu minutd oblongd, apice truncato et digitum minutum gerente; 2di 

 manu gimidi, subovatd, palmd obliqud, dimidio nianus parce longkxre, 

 integrd, spinulosd, carpo brevissimo, transverso, articulo 2>tio infra ob- 

 tusorectangidato, nudo, breviore quam articidus 2dus. Styli caudales 

 paucirspimdosi, ramo externo paris lmi nudo. 



Male: — Feet of third and following pairs as above. Inferior antennse 

 longer, and joints of flagellum three or more diameters in length. 

 Feet of first pair having a very small oblong hand, truncate at 

 apex and having a minute finger; of second pair, with a large hand, 

 subovate, palm oblique, a little longer than half the hand, spinu- 

 lous, entire, carpus very short and transverse, third joint below 

 obtuso-rectangular, naked, shorter than second joint. Caudal sty- 

 lets with a few spinules, outer branch of first pair naked.

 flagellum of outer antennae ; d, extremity of leg of first pair ; e, ibid, 

 of second pair; /, ibid, of third pair; g, ibid, of seventh pair; A, stylet 

 of first pair. 



New Zealand, but whether from the Bay of Islands or the volcano 

 of Taiamai, we are uncertain. 



The difference in the first pair of stylets, the outer branch being 

 naked in the male and not so in the female, is one point which sug- 

 gests a doubt as to the two being of the same species. If not the male 

 of the 0. sylvicola, it is, probably, male of the 0. tenuis.
