male is no longer present in his material. Examples of the true T. protensa, Walck., from 

 Mauritius (collected by Mr T. W. Eyre) are also present in the Brit. Mus. Coll., so that it 

 appears that both species occur in the island. 



21. Tetragnaiha modesta, n. sp. (Fig. 2). 



Colour. Carapace fawn colour ; maxillae, labium and sternum infuscate. 



Abdomen greenish, and densely sprinkled with minute whitish specks, its dorsal 

 surface marked with five pairs of dark lateral spots, which are arranged in two longitudinal 

 series. Legs greenish brown. 



Carapace very long and narrow ; the central impression and grooves 

 similar to those of T. geniculata Karsch. Median eyes occupying a 

 quadrate area ; the anterior medians larger than the posterior medians. 

 Posterior laterals a little smaller than the posterior medians, but slightly 

 larger than the anterior laterals ; the lateral eyes being separated from 

 one another by an interval which is greater than the diameter of a 

 posterior lateral. 



Fig. 2. Tetragna- 



Abdomen very long and slender. tha modesta, n. 



sp. Chelicera 

 Chelicera rather short, the first (distal) tooth of the ventral row from below. 



being of moderate size and separated by a considerable gap from the ten 



remaining teeth of the row, which form a continuous series ; the two distal teeth of 



the continuous series of fairly large size, but the others minute. The first tooth of the 



upper row is a little larger than the first of the lower, and, like it, is separated by a gap 



from the remaining teeth of the row, but the gap is much greater than is the case in the 



lower row. The remaining teeth of the upper row are five in number, and the distal one 



is of fairly large size ; they follow one another closely, progressively diminishing in size. 



Fang of chelicera furnished ventrally, at a little distance from its base, with a strong 



curved tooth, and also with a minute tubercle at the base (Fig. 2). 



Measurements in mm. Length of carapace 225, of abdomen 7. 



Material. A female specimen (the type) from Mahe\ and several others from 

 Silhouette. 



Remarks. This new species of Tetragnatha is very closely allied to T. geniculata, 

 Karsch (a species which occurs in Ceylon and India), but the fang of the chelicera is not 

 geniculate and the armature of the proximal segment of the chelicera is also a little 

 different. 



25. Argiope anasuja, Thor. (Fig. 3).

var. Jletcheri, n. var. 



This variety differs from the Indian specimens of A. anasuja preserved in the British
