Note: L. rara is broadly distributed in the tropical Atlantic and Indian Oceans (Nafpaktitis et al. 1977). 

 The species was first recorded from the tropical eastern Pacific by Beebe and Vander Pyle (1944); 

 subsequently, Wisner (1971) determined the Loweina species in the eastern tropical Pacific to be distinct 

 from L. rara, and named it L. laurae. According to Wisner (1971), "L. laiirae is basically quite similar 

 to L. rara (Liitken, 1892), differing primarily in the distinctly longer head, 29.0% of SL (27.3-30.7) vs 

 about 25.7%. The eye is also somewhat smaller (sic), averaging about 8% of SL (7.1-8.8) vs about 6% 

 (5.9-6.0) for L. rara." Measurements of 8 specimens from this survey, 14 specimens from the Atlantic, 

 and 10 paratypes of L. laurae, indicate almost complete overlap for both head length and eye size. 

 Average head length was 28.7% SL (range 26.5-30.8) for specimens from this survey, 28.0% (range 26.3- 

 31.5) for the Atlantic material, and 29.4 (range 28.1-31.6) for the paratypes of i. laurae. Eye size 

 averaged 7.1% (range 6.5-7.4) for specimens from this survey, 7.4% (range 5.9-9.0) for Atlantic material, 

 and 6.8%) (range 6.4-7.4) for L. laurae paratypes. Following Paxton et al. ( 1 995), we use the name L. rara 

 for the eastern tropical Pacific population of Loweina.
