LAOPHONTE HERDMANI, A. Scott. (Pis. XI. figs. 5-7 ; XII. 

 fig. u 1 ; XIII. fig. 7; XIV. fig. 8 ; XVII. fig. (J.) 



1902. Lnoplionte Henlmani, A. Scott, 1. c. p. 414, pi. i. fig. 15 ; 

 pi. ii. figs. 3-8. 



This species was also described from specimens obtained in 

 tbe Red Sea in the same gatherings with the last ; and we 

 have now to record its occurrence from Devon and Cornwall. 

 L. Henlmani has a fairly close resemblance to L. curticauda, 

 and though rather smaller than that species mav readily be 

 mistaken for it. The female represented by the drawing 

 (PI. XIII. fig. 7) measured '64 mm. in length, but the length 

 of the male was only '51 mm. 



The antennules of the female are six-jointed ; the first 

 three and the last are subequal in length and of moderate 

 size, but the other two are very small (PI. XII. fig. (>). 



The antennre and mouth-organs resemble those of L. curtl- 

 cauda. 



The first pair of thoracic feet have long and slender inner 

 branches ; the outer branches, which are also slender, are 

 short and three-jointed (PL XI. fig. 5). 



The second, third, and fourth pairs in the female and the 

 fourth pair in the male are somewhat similar to those of 

 L. curticauda, but the second and third pairs of the male are 

 distinctly different, especially as regards the inner branches ; 

 in the second pair the second joint of the inner branch 

 (PI. XI. fig. 6) is furnished with two marginal and two 

 terminal setae, but the hook-like appendage so characteristic 

 of L. curticauda is wanting, being replaced by a plumose 

 seta. In the third pair the inner branch appears to be three- 

 jointed, while the second joint ends in a moderately stout 

 spine-like process which extends beyond the extremity of the 

 third joint; the third joint bears four setae, two of which are 

 marginal and two terminal (PI. XIV. fig. 8). 



The fifth pair in the female are somewhat similar to those 

 of L. curticauda (PI. XVII. fig. 6). In the male the inner 

 portion of the basal joint is not produced and appears to be 

 furnished with only a single seta ; the secondary joint is 

 small, and provided with five setre on the subtruncate apex 

 (PI. XI. fig. 7)._ 



The furcal joints are about equal in length to the last 

 segment of the abdomen.

 St. Mary's, Scilly Islands, near Drake Island and other 

 places in the neighbourhood of Plymouth, not uncommon.
