58 MOLLUSCA. 
Hab. N. Guatemaia: Coban, dep. Vera Paz? !° (coll. Cuming}; Delattre ?~*, Salvin 8, 
Sarg"); Alta Vera Paz (Bocourt*, Boucard®) ; Purula, upper part of the Polochic 
Valley (Champion). 
CENTRAL GUATEMALA: Guatemala city (Champion). 
Rather variable in the relations of length and diameter, in the proportion of the 
last whorl to the whole length, in the size of full-grown specimens, and also in the 
presence or want of a light rounded angulation in the upper part of the last whorl. 
The var. 6 shows in the upper whorls no difference from the type; but the lower 
whorls are pale yellow instead of reddish-orange (without periostracum white), and the 
aperture is bordered by a narrow band of bright red. It is chiefly found at Coban, 
with the type. 
G. binneyana (Pfr. op. cit. iv. p. 638), Fischer and Crosse (op. cit. p. 93), and Strebel 
(op. cit. p. 27), probably belongs to the same species. Pfeiffer’s description and measure- 
ments agree well with a middle-sized specimen from Coban; he gives no locality, but 
Fischer and Crosse state that a specimen has been found by Mr. O. Salvin in Vera Paz. 
I have examined this specimen: it is very worn and belongs no doubt to A. fusiformis. 
The author’s description, ‘‘parum nitens, carnea,” is very applicable to a somewhat 
worn example, in which the colour has become more reddish. ‘The spiral lines, which 
are very fine in well-preserved specimens, having disappeared wholly in worn ones, 
Dr. Pfeiffer has placed his G. (Oleacina) binneyana in another division “ § 5, longi- 
tudinaliter striate vel costulate,” far from G. fusiformis, which is in “ § 6, decussate ” ; 
Strebel is the first who has recognized its close resemblance to G. fusiformis. 
The measurements of not quite full-grown specimens are :— 
Long. 70, diam. 31, apert. 45 millim.

considerable attenuation below. Mather solid.
