Locality. — Lower Burma: at Prome; one specimen, col- 

 lected by L. Fea and described by Thorell (Museo Civico, Genova). 



Remarks. — T. Gambridgei is easily distinguished from 

 all other species hitherto known by possessing real eyes with 

 a convex, vitreous cornea. — The specimen kindly lent me by 

 Dr. R. Gestro had been mutilated before Isawit; some time 

 after I had drawn the figures I intended to take measure- 

 ments, but during a change I dropped by mishap an objective 

 on the glass-cover which was crushed together with the animal 



— fortunately the head, the legs of importance and the flagellum 

 are still rather well preserved. 



Species of Tartarides not seen by the Author. 



Trithyreus {Hubhardia) pentapeltis Cook (Proc. Ent. Soc. 

 Wash., Vol. IV, N:o 3, May 24, 1899, p. 253, Pl. III, figs. 1 a 



— 1 n). This species was secured at Palm Springs, California. 

 According the Cook the body of the male, flagellum omitted, 

 measures 9.3 mm.: it must thus be the largest form of the 

 tribe hitherto observed. Cook describes and figures the adult 

 male and mentions an immature specimen; his figures of the 

 palps and of flagellum ought to have been much better, but 

 if his fig. 1 f, showing the foot of first leg, is tolerably correct 

 the species can be recognized with certainty. That his genus 

 Hid)bardia ought to be cancelled is proved above on p. 33. 



Artacarus liberiensis Cook. A real description of this West- 

 African form was ne ver published. On p. 33 I have shown 

 that the genus must be cancelled and the species considered 

 as a nomen nudum.
