SPECIMENS EXAMINED. 



J^(:marh.— This species in a general way resembles Z. hilgendorfi 

 Bohm, but may readily be distinguished from that species by the differ- 

 ently shaped proboscis, its length, absolute and relative to the palpi, the 

 restriction of the chitinous ridges, which in that species extend to the 

 ends of the legs, and, judging by Bohm's figures (Bohm, '79*, pi. 11, 

 fig. 3 d), by the differently shaped and armed second tarsal joint, as well 

 as by other marked differences. 



The structure of the ovigera in the male as compared with those in the 

 female is worthy of notice, the more complicated bending and the arma- 

 ture in the former being well adapted to keeping the egg-masses from slip- 

 ping off. One of the males examined (collected on November 26) had a 

 single egg-mass on one of this ovigera, while another specimen (collected 

 September 2) was carrying eight rather bulky globules. 



As mentioned above, the females are somewhat stouter than the 

 males, and in a specimen collected on December 29 large ova were to 

 be seen in the second and third coxal and femoral joints. 



Genus Ammothea Leach ('14). 

 Achelia Hodge, '64, p. 114. 



Trunk short, stout, segmentation usually suppressed ; lateral processes 

 closely crowded, making the body appear more or less disciform ; first 

 segment massive, with square frontal part. Caudal segment not sepa- 

 rated from last trunk segment by a suture, narrow cylindric, usually 

 horizontal. Eye tubercle near to the front of the first segment, 

 strongly protuberant, with distinct eyes. Proboscis directed obliquely 

 downward, constricted at the base, fusiform, often with an annular con- 

 striction near the distal end. Chelifori in fully developed specimens 

 very small, 2-jointed, second joint globose. The chelifori are chelate 

 in immature specimens. Palpi 8-jointed; y'.i and/.3 short; y.2 and/.4 



1 The numbers in thi.s column are those given to each lot of specimens of the same 

 species and from the same locality ; the original numbers of the collectors, when there 

 were such, are given in the column with the source.
