of its characters between Gonodactylus and Pscudosqnilla. Compare 

 Odontodactylus Jiavanensis (pi. xx) with Gonodactylus cliiragra on the 

 one hand and ^lih. Pseudosquilla ciUata on the other, and then compare 

 this hirva (fig. 2G) with a typical Goncrichthns and a tyjiical Pseude- 

 richtlms, as, for instance, the forms fignred by Brooks* on ])1. xii, iig. 0, 

 and on pi. xv, fig. 11, respectively. It Avill be seen that this larva 



(No. 4393, U.S.K.M.), which was WvO^ / 



taken at Woods Holl, Mass., August ^wCr'i//^~~~^ 



22, 1870, has the elongated body and ^-^^^y^ / 



short carapace of Pseud osquiUa, but ^%^l^^C^^^"Nx/ 



the carai^ace bears the long rostrum ,^!^^^^ \ y 



and long x)ostero-lateral spines of /^^n//^,.^...^^ 



a Goncrichthns, while the dactylus '^^^^^'^ 



of the raptorial limb shows traces 



of seven or eight lateral teeth. It 



is thus excluded from either of the genera with which we have been 



comparing it. Odontodactylus havanensis, however, has six lateral teeth 



upon the dactylus and 0. ha)isenii, recently described by Pocock (1893) 



has nine distinct teeth, so that our larva may well beloug to this genus. 



It probably belongs to some West Indian species, was swept north by 



the Gulf Stream and then driven into W^oods IIoll by a southerly wind, 



for such has been the fate of many tropical creatures. 



Brooks also found in the Challenger collections "larvaj which closely 

 resemble Pseuderichthus, although they may be Gonodactylus larvaj;" 

 perhaps they are younger stages of Odonterichthus.

At Bimini on the 7th of July, 1892, several Alimte were taken in the 

 tow net. The two largest ones appeared to be alike on a superficial 

 examination and were distinguished from the rest by the great elonga- 

 tion of the body in i^roportion to its width. One of these was i)reserved
