Found in dead coral. 



This species seems to agree with Leptochelia savignyi (Kr0yer), with 

 the exception that both males and females have the inner branch of 

 the uropoda composed of five articles instead of six. 



It seems best to keep this species distinct from Leptochelia savignyi, 

 although they are hardly to be distinguished except for the difference

in the number of articles to the inner branch of the uropoda. Tlhe 

 female of L. algicola has been placed in the synonymy of L. diibia by 

 various authors, notably Sars and Norman, and I have also previously 

 followed their example. Now, however, I am inclined to think, with 

 Dollfus, that both the male and female of L. algicola should be placed 

 in the synonymy of L. savignyi, inasmuch as they both agree in hav- 

 ing the inner branch of the uropoda six-jointed in both sexes, whereas 

 L. dubia in both sexes has the inner branch of the uropoda composed 

 of onlv five articles.
