MR. C. J. WITH ON" SOME NEW SPECIES OF 



Leg IV.: femur 1-150 (0-285), trochantin 0'345 ; tibia 1-081 (O'lGl) ; 

 tarsus I. 0-445 (0-138) ; tarsus ii. 0-368 (0-115) mm. 



Abdomen, etc. — A fairly distinct genital area is present. The rather short 

 galea extends only sHghtly beyond the terminal hair and has a few branches 

 (ef. 18. tab. ii. fig. 4 d). 



Palps. — The proportions are slightly different from those of the female, as 

 may be realised by comparing the measurements : the most important differ- 

 ence being that the hand is only I'T as broad as the tibia, 1-9 as long as wide, 

 and at least 1-2 as long as fingers ; its anterior outline is less strongly convex. 



Coxce. — The fourth pair are less slender, being only three times as long as 

 wide. 



Meamrements. — Cephalothorax 1-15 (0-92) ; abdomen 2*8 (1"7) mm. 



Palps: trochanter 0-552 (0-345); femur 1-288 (0-299) ; tibia 1-196 (0-322) ; 

 hand 1-035 (0-552), depth 0-495 ; finger 1-288 mm. 



Material. — I have examined a single male, four females, and two young- 

 specimens, of which one was probably newly hatched, all collected together 

 and I mounted, I with a label which reads: "Mustique Island, June; sandy 

 seashore under drift-wood ; each one in a thin round flat silken nidus, about 

 ^ inch in diameter, attached to lower side of log, (dose together. Two of the 

 females carried bundles of eggs." Previously mentioned from Florida. 



Remarks. — In spite of Banks's rather imperfect description, I do not 

 hesitate to refer the described characteristic form to his G. fioridensis, Bks. 



4. Olpium cordimanum, Balzan (cf. With, 18. fig. 1, p. 17, tab. 2. figs. 

 6 a— 6). 

 1891. Balzan, (6) pp. 536-537, pi. 12, fig. 28. 



In the main, I refer to Balzan's good and fairly complete description. The 

 galea extends somewhat beyond the terminal hair ; in the female it has about 

 five terminal teeth and is in the male without any teeth {cf. 18. fig. 1, p. 17) ; 

 the serrula exterior has all its teeth squarely truncate, of equal length ; and the 

 fiagellum consists of three hairs (18. tab. ii. fig. 6 Ii) ; the lamina interior has 

 a plate-shaped basal portion, three dentated lobes, and a long pointed terminal 

 spine (18. fig. 6 a). 



The femur of the palps has a " tactile " hair dorsally near the base and the 

 fingers possess a close row of marginal teeth; no "spots" are found anteriorly. 

 The rather short coxce are in the main like those of Olpium hirmanicum, With 

 (18. fig. 7/). 



The first tarsal joint of the fourth pair of legs has a basal " tactile " hair. 

 The legs are slender, especially the distal joints ; femur I. of the first pair 

 of legs is three times as long as deep and almost twice as long as the distal 

 femoral part ; the tarsal joints, of which the first is 1-2 as long as the second>
