small warts, and curved inwards against each other ; the 

 two inner lobes are so short that they do not fill the space 

 between the two outer ones, but a split is formed between the 

 latter, corresponding in position to the middle of the opening 

 between the terminal joints of the palpi of the maxillipeds. 

 This second pair of maxillss carries no palpus ; it does not 

 quite cover the first pair of maxillse, but only their lobes, the 

 stipes and cardo of the latter appearing on either side. When 

 separated from the other parts, each maxilla of the first pair is 

 seen to consist of a large, elongate triangular cardo, a very- 

 elongate, narrow, compressed-cylindrical stipes with con- 

 tracted apex, and furnished in the midst with sparse short 

 hair. The outer lobe is adnate to the stipes, narrow, hand- 

 shaped, without spines, but divided on the inner side into 

 seven long, pointed, somewhat incurved teeth, ranged in two 

 rows, the lower one being formed by the long and stout ter- 

 minal tooth, with the next following, which is more slender, 

 and a small, slightly outward bent one in the inner corner, 

 whilst the upper row is formed by four other teeth of middle 

 size ; there is no inner lobe nor palpus. When both these 

 pairs of maxillae are taken off, we perceive the tongue, which 

 is flat, thin, naked, dilated, broadly rounded at the apex, and 

 divided for more than half its length. The basal part of the 

 split of the tongue is elliptically widened, and placed just over 

 the middle of the opening between the maxillary lobes of the 

 second pair, which again corresponds with the middle of the 

 gap between the terminal joints of the palpi of the maxillipeds. 

 Above the tongue, finally, the lobes of the mandibles appear. 

 The outer one forms an irregular quadrangular or rather 

 broadly falcate leaf, of which the anterior outer margin and 

 the inner corner are somewhat thicker than the rest; the 

 margin is rather rounded at the apex, and carries inside this, 

 on the upper face, two broadly rounded flat teeth, one behind 

 and above the other, giving the apex the appearance of being 

 obtusely tiidentate ; the inner corner of the lobe forms a 

 large, flat, coniform, somewhat recurved tooth. The thin, 

 foliaceous inner lobe is fixed to the outer one, between the 

 inner corner and the apex of the latter ; its margin is curved 

 and cut out into about twenty small recurved exceedingly 

 sharp little teeth. 



A comparison between the structure of the mouth of An- 

 thtira, as just described, and that of Cymothoid^e discloses a 

 general resemblance to that we have described in ^ga, though 

 there are differences in subordinate points. The sucking- 

 tube is in both cases formed by the maxillipeds with the con- 

 currence of the upper lip, which applies itself .to them; but in
