i\H those of S. ima ; tlie first four joints are top^ether equal 

 to about Iwice tlie entire lengtli of tlie last four; first, second, 

 and fourth joints suhequal, but the second rather longer than 

 the other two ; third about half the length of the second and 

 nearly equal to the last ; the fifth, sixth, and seventh small, 

 as shown in the formula —

Antennas nearly as in >S'. ima ; outer ramus small, tri- 

 articulato. 



iSecond maxillipeds moderately stout ; second joint about 

 twice as long as broad, having a series of minute bristk-s 

 arranged horizontally on the lateral aspect and near the 

 nn'ddlc, and with a small but distinct seta on tiie iiuicr marfriii 

 and towards the distal end ; terminal claw moderatiily 

 slender. 



First pair of natatory legs moderately slender; the outer 

 branches reach to about the end of the first joint of the inner, 

 and the exterior spines are slender and elongated ; each of 

 the three joints fringed with minute cilia on the outer margin ; 

 first and second joints with also a number of delicate cilia on 

 the inner margin ; inner branches have the first joint rather 

 longer than the entire length of the second and third, while 

 the end joint is fully twice the length of the middle one. 

 The last pair are somewhat similar to those of S. ima, but 

 the secondary joints are proportionally broader, being about 

 half as broad as long ; there is also a slight difference in the 

 armature.

The more important differences between the species just 

 described and IS. ima^ which it resembles, are found in the 

 proportional lengtiis of the joints of tlie antennules, the 

 greater proportional length of the outer branches of the first 

 ])air of legs, and in the secondary joints of the fifth pair being 

 proportionally broader. 



Stenhelia neglecta, sp. n. 



Descrij)tion of the female. — This species is moderately 

 slender and about "8 mm. in length, liostrum moderately 

 elongated and slender. Tiie antennules resemble those of 

 IStetihtlia ima in length and number of joints, but the lengths 

 of the joints differ as shown by the formula —
