In June, 1940, the writer visited the Museum of Com- 
parative Zoology, Cambridge, Massachusetts, to examine 
certain type and other specimens of millipeds in the col- 
lection there. In the material seen was a recently received 
Cuban species of Amphelictogon, obviously differing from 
other known members of the genus. A description of this 
species follows. 
Also the opportunity is taken for presenting drawings 
made from a number of R. V. Chamberlin’s types of West 
Indian millipeds, especially those in the genus Amphelic- 
togon , where the difficulty of distinguishing the species 
without reference to illustrations of the gonopods has been 
found very great or, in certain cases, impossible. 
A species described by C. H. Bollman which, for over 
50 years, has erroneously reposed in the family Platyrha- 
cidae is here transferred to another family where a new 
generic name is proposed to admit it.

This is the only known member of the genus having the 
dorsal surface of its segments divided into definite quadrate 
or polygonal areas. A gonopod of the type is shown in figure 
d of the plate.
