meats. Cephalothorax narrow, somewliat triangular, much longer than broad, 

 with a higli elevated ridge each side, about parallel with the side margins, the space 

 between the ridges concave in anterior portion, convex behind; the anterior margin 

 of the elevated portion is rounded; each lower anterio-lateral angle of the cephalo- 

 thorax is prolonged into a conic tubercle, or horn, wliich is slightly longer than 

 broad at base. There is a trace of the jiosterior suture, but the anterior one is 

 very obscure; on each side there are two prominent eyes about their diameter apart, 

 the posterior one on a tubercle and looking backward. 'I'he abdomen is broad and 

 depressed, narrower at base than at posterior margin, broadest on the 6th segment, 

 the segments plainly divided. I'alpi long and slender; trochanter swollen on the 

 posterior side, anterior margin nearly straight; femur short-pedicellate; cylindrical, 

 much longer than cephalothorax; tibia gradually enlarged from base to near tip, 

 :d)Out as broad and nearly one-half as long as the femur; neither margin much 

 convex; claw as long as femur, hand about one and one-half times as broad as 

 femur, nearly cylindrical, and about twice as long as broad; fingers much longer 

 than hand, very slender and nearly straight. Legs about as usual, but no trochan- 

 tins visible on the posterior hairs. All hard parts coarsely granulate; no hairs on 

 palpi, except fine ones on fingers, a few thick ones on the legs with fine ones on tarsi. 



This interesting species was found by Mr. Hubbard between 

 tlie laminae of rocks at Specimen Ridge, Yellowstone National 

 I'ark. Many were young and had formed little cases of silk and 

 earth, in which to pass the moulting period. The structure of 

 these young forms is not, however, different from that of the adult. 

 This species might, on account of the structure of the cephalo- 

 thorax and the absence of trochantins, form a new genus. 



Qarypus floridensis, sp. nov. 



Length, 4 mm. Body pale brown, legs and palpi, except claw, pale liiownish 

 yellow, claw red-brown. Cephalothorax with mandibles triangular, longer than 

 broad, very much narrowed in front, anterior margin emarginate and about one- 

 fourth as long as posterior margin; sutures distinct; two eyes each side nearly 

 touching, the posterior one looking backward. Abdomen depressed, much broader 

 behind than in front, broadest on 7th segment, scutEe short and quite broadly divi- 

 ded. Palpi moderately slender; trochanter swollen behind, convex in front; femur 

 gradually enlarged from base to tip, slightly longer than the cephalothorax; tibia a 

 little pedicellate, enlarged from base to near tip, about two-thirds as long as femur 

 and a trifle broader, neither margin much convex; claw pedicellate, longer than 

 femur, hand about as long and nearly twice as broad as tibia, somewhat cylindrical; 

 fingers about as long as hand, and plainly curved. Hard parts finely granulate, 

 and with short, fine, scattered hairs. 'I'rochanlins quite plain on posterior legs. 



Several specimens of this large species were collected by Mr. 

 Hubbard under drift-wood on the ocean beach, near St. Lucie 

 River, Indian River, Florida, in April i<S8o.
