Bathyphantes calcaratus, new. (Plate IV, figures 18, 13a.) 



This species lias been found at Portland, Maim-, Moosehcad Lake, 

 and the lower part of Mt. Washington. The largest measures 3 mm. 

 long. All the specimens are distinctly marked with gray, the darker 

 one resembling Drapetisca socialis. The legs are long and slender, 

 the femur darker toward the tip, and the tibia and metatarsus dark 

 at the end and in the middle. The cephalothorax has a dark spot 

 in the middle, wide in front and tapering to a line behind. The 

 abdomen is white and gray, the markings of the front half united 

 into a middle stripe with broken edges and two narrow lateral 

 stripes. On the hinder half the markings are in pairs, slightly con- 

 nected in the middle. The male palpi are as long as the cephalo- 

 thorax. The patella and tibia are both short, but the tarsus is 

 elongated with a short and sharp spur at the base. The tarsal 

 hook is very large, recurved and widened at the end, where it has 

 a short point above, and a longer one below, as shown in the figure. 

 The tarsal hook resembles that of Microneta crassimanus, a larger 

 and shorter legged spider. 



Microneta persoluta. (Plate IV, figures 11, 11a.) 



The old figures in N. E. Therididse do not give a correct idea 

 of the form of the tarsal hook, though they do show its character- 

 istic sinuous lower edge. The tarsal hook is turned outward and 

 thickened at the end, where it has several blunt irregular teeth as 

 shown in the figure. It has been found at several new localities 

 and seems to be a common species. 



Microueta denticulata, new. (Plate IV, figure 14.) 



This species resembles closely M. persoluta in size and color, and 

 is found in company with it, but is easily distinguished by the palpi, 

 PI. IV, fig. 14. The tarsal hook is nearly horseshoe shaped and has 

 a thick edge on which are six or moreprominent teeth, those near 

 the base partly united. The parts of the palpal organ are longer 

 and more separate than in persoluta. The mandibles are without a 

 prominent tooth on the front. 



Microneta latidens, Emerton. Trans. Conn. Acad., 1892. (Plate IV, 

 figures 12 to 12 c.) 

 The male of this species was described in 1882 from New Haven, 

 Connecticut. Since that time both sexes have been found at several 

 places and in large numbers. It is 2 mm. to 2.5 mm. in length, 

 the females being usually a little smaller than the males. The
