species, perhaps presenting merely a variety. It differs, however, 

 ver}" notably in the character of the median lobes, wliich in ijyri 

 are of the normal Parlatoria type, with a deep prominent outer 

 shoulder on each of the lobes. It also differs from pyri in the pres- 

 ence of the chitinized processes or paraphyses, which in pyri are 

 usually wanting or only faintly indicated, and in the practical absence 

 of the smaller pores, which in ^J^/H ai'e found rather abundantly 

 near the margin of the anal and other segments. The anal plate is a 

 little more heavily chitinized, thus bringing out more pronunently 

 the basal and ventral thickenings. It occurred very scatteringly, 

 altogether but four females being secured. Like pyri, the tip, at 

 a superficial glance, reminds one strongly of perniciosus, the effect 

 being produced by the very much smaller, lower, and closely placed 

 second lobes. This species diverges still farther than pyri from 

 the normal Parlatoria characters. The sparsity of plates and the 

 practical absence of the branched plates along the margin of the anal 

 and other segments, and the sparsity of submarginal and marginal 

 pores, are all features wliich differentiate it from the normal type of 

 Parlatoria. The broad lunar marginal pores of the anal segment, 

 however, are distinctly of the Parlatoria character, and the secretions 

 and exuviae are distinctly those of Parlatoria.
