87. Oethopoki's grenadae, sp. nov. 



Tijpe.— M. C. Z. 4,335. Grenada: Richmond Hill, August 25, 

 1916. 



This species is close to 0. aniiUanus and possibly was embraced under 

 that name by Pocock who records it from Grenada as well as from St. 

 Thomas. It differs from the form of which the gonopod is figured by 

 Pocock in having the distal lateral process or spine much smaller and 

 extending distad or a little mesad of distad instead of directly ectad; 

 the funnels are also carried farther distad and closer to the principal 

 part than indicated in the figure mentioned, with the tube more 

 strongly bent; the median proximal piece is very similar, being less 

 strongly arched, distally less angular. The coloration and sculptur- 

 ing as in the latter species. The body is considerably more slender. 



Number of segments (male), sixty. 



Length near 100 mm. ; width, 5.25 mm. 



88. Orthoporus haitiensis, sp. nov. 



Tijpc.— M.. C. Z. 4,336. Haiti: St. Marc, January, 1913. W. M. 

 Mann. 



A much smaller species than the two above described and than 0. 

 nitidus and 0. aniiUanus. Near 0. ventralis in structure though 

 likewise much smaller than that form. Body strongly narrowed 

 cephalad. Somites black about middle, the anterior and posterior 

 borders ferruginous. Legs ferruginous. A dark band extending 

 across face between eyes and antennae, this embracing a pale spot in 

 each lower corner. Collum bordered all around with black. 



Differing from 0. ventralis in having the eyes smaller, composed of 

 fewer ocelli, and separated by nearly twice their diameter instead of 

 only once. Vertigial sulcus fine. 



Collum in side view showing below J;wo very deep sulci above the 

 submarginal one, the upper one curving upward within the anterior 

 margin. Not dilated below as in 0. ventralis. 



Striae of most segments falling much short of extending up to the 

 pore. 



Anal scutum caudally rounded; caudal portion depressed and 

 roughened, coriaceous, the principal portion minutely subdensely 

 punctate. Anal valves mesally strongly compressed and elevated. 



Number of segments, fifty-five. 



Length near 52 mm.; width, 4.2 mm.
