described by Moreira! as divergens I have not seen, nor am I altogether 
assured that it represents a distinct form.

Clibanarius chapini, new species 
Text Figures 70 and 71 
Type Locatiry.—St. Paul de Loanda, October 21, 1915, 70°, 52 (lovig.); 
October 23, 1915,2<7, 19. (Amer. Mus. No. of type 4798.) 
MEASUREMENTS.—Of male holotype, length of anterior portion of carapace 5.1 
mm., width 4.1 mm., longer eye-stalk 4.8 mm. long. 
Description.—An apparently new species which I cannot reconcile with the 
descriptions of any of the Clibanarii so far recorded from West Africa. 
In some respects it seems to resemble C. virescens Krauss,’ but aside from striking 
color differences, the relative length and proportions of the eye-stalks at once separate 
the two. The eye-stalks of virescens are about six and one-fifth times more or less 
as long as wide, while their length in chapini approaches eight times their width at 
the middle. 
The eye-stalks of C. chapini are slightly shorter than the antennular peduncles, 
but exceed the antennal peduncles by about the space occupied by the cornea, or a 
little more; they are about one-seventh to one-eighth longer than the greatest width 
of the anterior portion of the carapace. The ophthalmic scales are more squarish in 
outline and more deeply incised with spine-like denticulations than in virescens, 
where the scales are rather more triangular with fewer and less prominent teeth. The 
antennal scale extends a little way beyond the base of the terminal segment of the 
antennal peduncle; the acute rostral projection of the front extends well in advance 
of the lateral antennal projections, which are armed with a spiniform tubercle at, or 
just below the anterior margin; the anterior portion of the carapace is about four- 
fifths as wide as long. .
