Discussion. — Several parts of Wilson's original description (1911b) 

 need to be mentioned and characteristics that he did not describe 

 should be discussed. These are characteristics noted not only on 

 the Hawaiian material but also on the original type material. Wilson 

 does not figure or describe an accessory process on the third segment 

 of the antenna but a setule-like process is present in the female 

 and 2 are present in the male (figs. 36c, d). The postantennal process 

 is composed of 3 nodules, each bearing several hairhke processes, as 

 well as a spinule-)ike projection. There is a great deal of variation 

 in the spinelike projection forming the postoral process; basically, 

 it is bifid in the female and simple in the male, but some of the female 

 specimens in the collections of the U.S. National Museum have a simple 

 process, while in others the process is bifid on one side and simple on 

 the other (see discussion of Gloiopotes huttoni for similar case). Wilson 

 indicates that the endopodite of the third thoracic leg is 3-seginented 

 although in all of the specimens examined, including the type mate- 

 rial, the endopodite is 2-segmented. There is a cuticular break in 

 the second segment in all of the specimens (fig. 36^) but this break 

 is incomplete and there is no indication of a 3-segmented condition, 

 either in the cuticle or by the associated musculature. 



Wilson deposited a series of cotypes (USNM 39613) in the type 

 collection. One of these (a female, USNM 39613) has been selected 

 as the lectotype, a second (male, USNM 112846) as the allolectotype, 

 while the rest (USNM 112847) have been designated paralectotypes. 



Rangnekar (1956) described the only other species in the genus, 

 M. carangis. The feature which best distinguishes the two species 

 is the presence of posterior lobes on the second segment of the abdo- 

 men of M. lobodes and their stated absence in M. carangis. A second
