Notes 



'^'Rios and Carvacho (1982) reported L. parvulus 

 (Stimpson) from the Gulf of California, and stated 

 that L. antiborealis could be a synonym of the former 

 species. However, they gave no justification for the 

 synonymy. The two species are treated here as am- 

 phipanamic sibling species. 



^-^Hippolyte mexicana Chace, 1937 is a synonjTn (Wick- 

 sten 1983). 



'^^Thor algicola is a sibling species of T. manningi 

 Chace, 1972. It was misidentified as T. pa^ichniis 

 (Heller) in previous works. 



^-'^^Thor amboinensis has been collected at Isla 

 Manuelita, Cocos Island, 20 m, among coral slabs and 

 rock, 16-25 November 1989, Alex Kerstitch, 1

^^^Eiialus lineatus has been given the name E. herd- 

 mani in the past due to confusion with Heptacarpus 

 herdmani (Walker) (Wicksten and Butler 1983). 

 Eualus subtilis Carvacho and Olson, 1984 also is a 

 synonym (Wicksten 1988).
