THETIS SCIENTIFIC RESULTS. 



Mandibles stout, the width at the summit being equal to half the 

 length, cutting edge broad, simple, subtended below with a few 

 spines and several spinules. Molar tubercle obtusely conical, 

 apically furnished with branched and simple spinules. Palp three- 

 jointed, the first short and stout, the two following are equal. 



Anterior maxillee with masticatory lobe, elongated, tipped with 

 simple curved spines ; inner lobe with four branched sette, the 

 internal one beina: much the longest. 



Posterior maxillee with the inner lobe rather broader than 

 either of the two outer. 



Maxillipedes slender. 



First pair of legs shorter and stouter than those succeeding. The 

 fourth, fifth and sixth joints are each armed on the inferior border 

 with three stout spines, which are very unequally bi- or trispinose 

 at their apices. Seventh joint terminated in two unequal spines, 



separated by a long stiff setse. 

 Peduncles of pleopods armed 

 on their inner distal angles with 

 several spines. Outer ramus of 

 the second pair obovate ; inner 

 ramus triangular ; the stylet is 

 fusiform in shape, one-third 

 longer than the ramus, and quite 

 glabrous. The outer ramus of 

 the last pair terminates in a 

 broad rounded lobe covered with 

 rasp-like teeth ; another similar 

 lobe is present on the inner 

 aspect below the sutural line. 

 Basal joint of the uropods 

 broader than long, obtusely 

 pointed on the inner side ; last 

 joint styliform, about equal to 

 the peraeon in length ; colour 

 white, and in strong contrast to 

 the rest of the body. The female
