BRUES: NEW SPECIES OF PERIPATUS. 317 



folds, which number 24 to a segment in place of 12 as in all other forms 

 (Plate 2, figs. 3-4). The number of legs is also greater than in any 

 other species except P. torquatus, a species occurring in Trinidad. 



As previously mentioned it occurs with P. juliformis, var. swain- 

 sonac, but is much rarer. Two mutations, or dimorphic color types 

 have been distinguished, gossei Ckll. with the tips of the antennae 

 white, and bouvieri Ckll. with the antennae entirely dark colored. 

 Both are represented among the eight specimens I have seen, each 

 type by four individuals. Bouvier, however, records gossei, with 

 the tipped antennae as by far the more common form. In all that I 

 have seen there is a curious correlation between the body color and 

 the variegation of the antennae. In the four with tipped antennae, 

 the body is uniformly brownish or purplish gray, almost black while 

 in those with uniformly colored antennae, the body is much paler, 

 almost tan colored, and apparently much faded in the alcoholic speci- 

 mens, till parts of the body are extremely pale. In these the antennae 

 however, appear not to be faded and are entirely blackish. Such 

 differences between the two forms do not appear to have been noted, 

 and may be accidental, although the exact agreement of four specimens 

 of each kind would make it appear to be quite a constant difference 

 in pigment as affected by alcohol, although not noticeable in living 

 individuals, which are all uniformly dark. 



Concerning the distribution of Peripatus jamaicensis little is known, 

 as the species has been found so far only in a very restricted area near 

 the eastern extremity of Jamaica. The present specimens are all 

 from Bath, the locality to which most of Bouvier's collected records 

 relate. 



A Peripatus from British Honduras. 



Hitherto no Peripatus has been recorded from British Honduras, 

 but the Museum of Comparative Zoology contains a single specimen 

 obtained by Dr. A. M. Tozzer while in charge of an expedition to 

 Central America in the interest of the Peabody Museum. The speci- 

 men was collected by Rev. Father Stanton at Benque Viejo. 



Unfortunately the preservation of the specimen is such that it is 

 impossible to determine its affinities. There are thirty pairs of legs 

 which would agree with P. biolleyi Bouv., but the integument is so 

 bleached and otherwise altered that I have not been able to discern 

 the structure of the dermal papillae or nephridial tubercles upon which 

 the correct determination must depend.
