1. Muraena dovii Giiuther. 

 {Alurwiui pUitUa Jor. & Gilb.) 



30480. A young specimen from Espiritu Santo Island, agreeing fairly 

 with the original description of Murcvna pintita^ but the tail slightly 

 shorter than the rest of the body. There are a few small yellowish spots 

 on the posterior part of the head, similar to those on the body, which 

 are not very numerous. 



We have examined two very large eels (19893) collected by Captain 

 Hereudeen at the Galapagos Islands. They seem to be referable to 

 Murccna dovii., agreeing as well with Giinther's description as they do 

 with each other, and there seems to be little room for doubt that our 

 '■'■ Murwiia pintita''^ is the young of the same species. There is consider- 

 able variation in the size and form of the small pale spots. 



2. Leptocephalus* conger (L.) J. «fc G. 



30930. A small specimen, 6^ inches long, from near Cape San Lucas, 

 does not show any variation from Mediterranean examples of this spe- 



*Tbe generic names Leptocephalus Giuelin (Syst. Nat. 1, 1150, 1788; based on Lepto- 

 cephalus morrisi, a larval Conger) and Echelus Ealinesqiie (Caratteri di Alcuni Nuovi 

 Geueri, etc., 1810, 64; E. macropterus Raf.) bave priority over Conger Cuvier. As Lep- 

 tocephalus is tbe first generic name applied to tbis group, it sbould in our opinion be 

 retained, in i)refereuce to Echelus, notwitbstanding its common use for larval forms 

 generally.
