180 Mr. A. White on a new genus of Arachnida. 



Deinagnatha, White, Dieffenb. N. Zealand, ii. 271. This 

 subgenus of Tetragnatha may be distinguished by the following 

 characters : — 



Chelicera longer than the cephalothorax, narrowest at the base, 

 with five spines at the end, the three on the upper side larger 

 than the rest : inner edge with two rows of small teeth, the un- 

 der row containing more than the upper ; the claw is very long 

 and* curved at the base, the tip is slightly bent. 



Eyes eight, placed on two slightly lunated parallel lines, the 

 two middle eyes of the anterior line nearer each other than they 

 are to the side eyes ; they are placed on the sides and the base of 

 a slight projection. 



Maxillce long, sinuated on the outer margin, dilated at the 

 ends, which are abrupt and very slightly rounded on the angles ; 

 palpi with the second joint very long, the third thickest at the 

 end, and shorter than the fourth, which is hairy and consider- 

 ably thickened at the end ; the globular process in the male, 

 near the base of the fifth joint, much as in Dolomedes mirabilis 

 (Clerck, Ar. Suec. t. 5. f. 4), only much more complicated. 



Mentum rounded at the end, with an impressed line near the 

 margin and extending round it ; there is a slight impressed line 

 down the middle. 



Cephalothorax of a longish oval figure, narrowed in front, de- 

 pressed, with two deep impressions about the middle. 



Legs long, first pair the longest, the fourth seemingly longer 

 than the second, the third very short. 



Deinagnatha Daindridgei,White, I. c. Ann. and Mag. PI. II. f.5. 

 Brownish yellow, hooks of chelicera and ends of the legs darker. 



Hah. New Zealand. 



Mr. Joseph Daindridge or Dandridge lived about the begin- 

 ning of the last century in Moorfields. Bradley, in his ' Philo- 

 sophical Account of the Works of Nature/ published in 1721, re- 

 fers to his having " observed and delineated a hundred and forty 

 different kinds of spiders in England alone." In the British 

 Museum, among Sir Hans Sloane's MSS., is a volume of Dain- 

 dridge's descriptions and figures; they are 119 in number, and 

 are all copied by Eleazer Albin, with but little alteration and no 

 acknowledgement, in his ' Natural History of Spiders/ published 

 in 1786. 



On PI. II. fig. 6. is figured a spider of remarkable form sent 

 by the Rev. D. F. Morgan from Sierra Leone ; it was described 

 in the ' Annals and Magazine/ vol. vii. p. 476, under the name 

 of Homalattus pustulatus.
