Saiissiirc's specimens were from the Antilles. (XT Tm't H-I- 



(Stimpson). 



The single small specimen, which I refer t> Sans-urr'- apecies, 

 without niiich doubt. w&B dredged mi the < 'hallenger I'.ank by the 

 |iartv from the Iliolo-'ical Station, in !'. 



In proportions ami general appearan<-e it resembles /'. r,, nrt.il, >//. 

 with which it was at first th.-n-lit to be identical by IMC and others. 

 The latter is not a I'hiti/lniiifn-ii*. 



It differs considerably from Stimpson's original description* of 

 P. Poiirtnltrii; ill tlic form of the rostrum, areolation, t uberdes, and 

 form of the carapace, number and charai-ter ..f ( he marginal teeth 

 and of those on the cheliped-. etc.

It should be noted that the figure- -iven by A. .M.- Kd \\ ard- do 

 not auree very well \\ith Stini]>son'. de-eript ion.-f M.-Md\\ ar-U' 

 fjo-iii'es show a decidedly larger number of tubercles on the carapace; 

 more numerous lateral teeth; two, instead of one, lame posterior 

 spines; more denticles on the dieliped-: a broader rostrum. It may 

 well be doubted whether he really had the -ame specie-, unle-s his 

 figures are very incorrect or the specie- remarkably variable. Our 

 specimen comes nearer to Stimpson's type, in s..m ( . respects, than to 

 M ."-Ed wards' figures. I5ut it agrees much better with Saiis-nre's 

 figure. 



Prof. S. I. Smith, in 1 *- 1, described and figured} a \ cry similar 

 form from deep water off the eastern coast of the I'nited States. 

 under the name of /.. JY/v ////'/'. 



* Stimpson's types of Crustacea were destroyed in the j^reat Chii-a^n Khv. 



t The description in Edwards' work is a men- tran.-lation f Stiinps-nn's and 

 does not agree with the figures. 



\ This same figure has been nsed by Miss Ji'ithbun, without rn-dit. ! illn-tiai.' 

 L. Pourtctlesii (Amer. Natnr. , xxxiv, p. 515, fig. 11). She considers the two 

 identical.
