As no author has separated the two species of this group from one another, and as 

 L. orientalis is much more common in the Indian Ocean than L. typics, all localities found in 

 the literature on the occurrence of a species with long eye-stalks in that Ocean or in the 

 Pacific must be discarded as without value.

Description. — Very similar in aspect to L. typus. The eye-stalks are still slightly 

 longer, as the distance between their insertion and the labrum is only about one-tenth as long 

 again as eye-stalks with eyes. The ventral processes on sixth abdominal segment in the male 

 (fig. 'ja) about as in L. typus, excepting that the swollen distal half of the posterior process is 

 bent feebly upwards, conspicuously less than in L. typus. The male telson (fig. 7 d) has the ventral 

 protuberance more semiglobular with the middle part of its lower margin more convex than in • 

 L. typus, furthermore the lower margin of the telson behind the protuberance is very short, 

 twice or three times shorter than in L. typus, and the posterior pair of dorsal spines are situated
