238 RETORT UNITED STATES GEOLOGICAL SURVEY. 



41. Audi ura /uniform is Meek. 



This species was found associated with No. 30, at Coalville; and also 

 in the Cretaceous sandstones at Old Dear River City, sonic thirty-five 

 miles to the northeastward, where it is associated with 1 noce w 'am ua prob- 

 lematic us &c. 



42. Turritella coalmllensis Meek. 



This, together with Nos. 33, 34, 36, 43, 44, 45, 48, and other species, 

 was found in a calcareous sandstone layer in the first ridge of Mr. 

 Meek's section at Coalville. It has also been found in (Southern Utah. 



43. Turritella spironema Meek. 

 See remarks under No. 42. 



44. Turritella (Aclis ?) micronema Meek. 

 See remarks under No. 42. 



45. Turbonilla {Ghemnitsia f) coalmllensis Meek. 



This form is much like those in the Laramie beds of Bear Eiver Valley 

 which Mr. Meek and myself have referred to Goniobasis. None of the 

 Coalville specimens are entirely perfect, but, so far as I can see, their 

 marine associates only, suggest the impropriety of classifying them 

 generically with the Laramie fossils just mentioned. 



46. Fulimella f inconspicua Meek. 



This, together with No. 35 and other species, was found by Mr. Meek 

 in stratum No. 16 of his section at Coalville, associated with brackish 

 and fresh water forms. See remarks under No. 29. 



47. Fulimella ? chrysalis Meek. 



See remarks under Nos. 29 and 45. 



48. JEulimella ? funicula Meek. 



This species, unlike the two next preceding ones, which have been 

 referred to the same genus, has marine associates only, having been 

 found at Coalville only in a layer of calcareous sandstone in the first 

 ridge of Mr. Meek's section. I described and figured a form from the 

 North Fork of Virgin Eiver, Utah, in vol. iv Expl. & Sur. West of the 

 100th Merid., and referred it to this species, with which it is probably 

 identical. It was there associated with a form which I referred to 

 Adinetopsis gregaria Meek, and the two species are also found associated 

 together at Coalville. 



49. Valvata nana Meek. 



This little shell was discovered by Mr. Meek in stratum No. 16 of his 

 Coalville section. See remarks under No. 29. 



50. Fusus (Reptunea f) gabbi Meek. 



This and the following species were found in the sandstones of the 

 second ridge of Mr. Meek's section, and, so far as I am aware, they have 

 never been recognized at any other locality. 



51. Fusus (Neptmiea) utaliensis Meek. 

 See remarks under No. 49. 



52. Admetopsis rhomboid es Meek. 



This form and No. 53 are associated together at Coalville, and I be- 

 lieve them to be specifically identical. 



53. Admetopsis gregaria Meek. 



See remarks under Nos. 48 and 52,
