A comparison of the types of Guerin and of Randall shows the spe- 

 cific identity of the two so-called species. Guerin's figure is poor, 

 that of Dana is far better. The bottle containing Guerin's type bears 

 the label (in his handwriting) "303 Alpheus lottini. Guer. Voy. Coq. 

 Edw. 2. 353, He de France ;" while the manuscript catalogue of hjs 

 collection (which was purchased by Dr. Thomas B. Wilson, and by 

 him presented to the Academy of Natural Sciences of Philadelphia) 

 has " 303 A. lottinii Guer. Voy. Coq. Edw. 2. 353 (type) Nouvelle Ir- 

 land, 1 Alk." In the published description Nouvelle Irland is given as 

 the locality. Under these circumstances I am inclined to believe that 

 the locality " He de France " was a slip of the pen.

This in all probability is the same as the preceding. Guerin's de- 

 scription runs: " Tres voisin de 1'A. ventrosus, Edw., p. 352. II en 

 differe par ses pattes machoires externes qui ne sont pas larges et 

 obtuses au bout, mais qui sont, au contraire, larges a la base du 

 dernier article, avec son extremite effilge et aigiie ; par 1'article basi- 

 laire des antennes externes qui porte une forte epine atteignant 

 presque la moiti de la piece lamelleuse du pedoncule."
