any anterior hard appendage. See Trans. Conn. Acad. 1894. The 

 palpus has the tarsus shaped as in pnmilns. At the base of the 

 palpal organ on the inner side the process is longer and sharper 

 at both ends than in pmnilus. Figures are given of this process in 

 the four species of Pedanostethus. PI. I, figs. 3, 3a, 3b, 3c. 



Ceratinella sphaerica, new. 



Males 1 mm. long. Cephalothorax as wide as long and two-thirds 

 as high in front as it is wide. Abdomen round, as wide as long 

 and nearly as high, extending forward over the cephalothorax half 

 its length. Hard covering of the abdomen extending underneath as 

 far as the pedicel and the spinnerets, and covered as in other species 

 with minute pits and hairs. PI. I, figs. 4, 4 a. The color is dull, the 

 cephalothorax and abdomen nearly black, and the legs 3'ellowish 

 gray. The sternum is wider than it is long and between the fourth 

 coxse as wide as it is in front. The male palpi are as long as the 

 cephalothorax. The patella and tibia are of the same length and 

 the tibia but little widened at the front. The outer process is 

 slightly curved outward and downward. Fig. 4 c. The palpal organ 

 is of the usual structure in the genus, with all the parts of moderate 

 size and length. Fig. 4 b.

Ceratinella carinata, new. 



Like C. laetabilis except in the palpi of the male. The palpi have 

 the tibia narrower than in laetabilis^ not more than twice as wide 

 as long and the wide black tooth is a fourth smaller. The tarsus 

 has on the outer edge three dark ridges that from some directions 

 look like spines and between the two outer ridges are a few minute 

 hairs. The whole tarsus is slightly smaller than in laetabilis. All 

 the males found in a bog at Springfield, Mass., and near the Wayside 

 Inn in Sudbury are of this species. In Concord, Mass., this and laeta- 

 bilis were found together. The tarsus of the male palpus of C. laeta 

 has ridges on the outer edge similar to those in carinata. PI. I, 

 figs. 5, 5 a, ob, 5 c, show the tarsus and tibia of males of this species 

 compared with laetabilis, laeta and briinnea.

2 mm. to 2.5 mm. long, more slender than G. ornata and with 

 longer legs. The palpi of the male are as long as the cephalo- 

 thorax, while in ornata the}' are shorter. The color is generall}' 

 lighter than in ornata, the head is lighter than the thorax, while in
