Tricholita chipeta, n. sp. — $ 32 mm., 5)^ 35 mm. 



In many collections will be found specimens of a species of 

 Tricholita from Colorado, under the name o( fistula, Harv., most of these 

 came from either Mr. Bruce or myself At the time these were distributed 

 I had no specimens of Harvey's species from California, from which 

 locality the types originally came, and so had no reason to doubt the 

 correctness of the identification. Having recently, however, received 

 specimens from California which agree much more nearly with Harvey's 

 description, I feel certain they are the true fistula, and that we have in 

 the Colorado specimens a distinct species. There is no question but 

 that the two species I have before me are perfectly distinct. In a series 

 of eight specimens from Colorado, evenly divided as to sex, the following 

 variations from the Californian ones are constant : The arrangement of 

 the white spots in the form of a pipe (mentioned by Harvey) is very clear 

 in the Californian specimens, in the Colorado ones the upright row of spots 

 is more rigid, not so curved, and the inner spot corresponding to the bowl 

 of the pipe is in all the specimens prolonged inwardly as a sharp spur 

 varying in length, in some specimens reaching as far as the inner edge of 

 the orbicular, it is bordered above and below by a more or less distinct 

 black line. The claviform is plainly marked, neatly outlined in black in 

 all Colorado specimens, while no trace of it can be seen in the others. 

 The orbicular is drawn out in a longitudinal direction, and in some 

 specimens is continued quite a distance inwards towards the base, in other 

 specimens there is a single black line running inwards from orbicular. In
